| VAR-200511-0018 | CVE-2005-3672 | Multiple vulnerabilities in Internet Key Exchange (IKE) version 1 implementations |
CVSS V2: 5.0 CVSS V3: - Severity: MEDIUM |
The Internet Key Exchange version 1 (IKEv1) implementation in Stonesoft StoneGate Firewall before 2.6.1 allows remote attackers to cause a denial of service via certain crafted IKE packets, as demonstrated by the PROTOS ISAKMP Test Suite for IKEv1. NOTE: due to the lack of details in the Stonesoft advisory, it is unclear which of CVE-2005-3666, CVE-2005-3667, and/or CVE-2005-3668 this issue applies to. Numerous vulnerabilities have been reported in various Internet Key Exchange version 1 (IKEv1) implementations. The impacts of these vulnerabilities may allow an attacker to execute arbitrary code, cause a denial-of-service condition, or cause an IKEv1 implementation to behave in an unstable/unpredictable manner. Stonesoft StoneGate Firewall and VPN Client are prone to multiple unspecified vulnerabilities in its IKEv1 implementation. Potential issues include denial of service attacks, format strings, and buffer overflows.
These issues were discovered with the PROTOS ISAKMP Test Suite and are related to handling of malformed IKEv1 traffic. Stonesoft StoneGate Firewall is a firewall.

CVSS V2: 5.0 CVSS V3: - Severity: MEDIUM |
Multiple unspecified vulnerabilities in the Internet Key Exchange version 1 (IKEv1) implementation in multiple Cisco products allow remote attackers to cause a denial of service (device reset) via certain malformed IKE packets, as demonstrated by the PROTOS ISAKMP Test Suite for IKEv1. NOTE: due to the lack of details in the Cisco advisory, it is unclear which of CVE-2005-3666, CVE-2005-3667, and/or CVE-2005-3668 this issue applies to. Numerous vulnerabilities have been reported in various Internet Key Exchange version 1 (IKEv1) implementations.

Various Cisco IOS, PIX Firewall, Firewall Services Module (FWSM), VPN 3000 Series Concentrator, and MDS Series SanOS releases are prone to denial of service attacks. These issues are due to security flaws in Cisco's IPSec implementation. The vulnerabilities may be triggered by malformed IKE traffic.
Successful attacks will cause most affected devices to restart. For Cisco MDS Series devices, this is limited to causing the IKE process to restart. IP Security or IPSec (full name Internet Protocol Security) is a set of IP security protocols established by the IPSec group of the Internet Engineering Task Force (IETF). Access control, data source address verification, data integrity check and prevention of replay attacks. Vulnerabilities exist in the handling of IPSec IKE messages in several Cisco products. IPSec's PROTOS test suite can test the design limitations of IPSec implementations by sending malformed IKE messages to target devices.

| VAR-200608-0043 | CVE-2006-0395 | Mac OS X of Download Validation Vulnerable to arbitrary code execution |
CVSS V2: 5.1 CVSS V3: - Severity: MEDIUM |
The Download Validation in Mail in Mac OS X 10.4 does not properly recognize attachment file types to warn a user of an unsafe type, which allows user-assisted remote attackers to execute arbitrary code via crafted file types. Apple has released Security Update 2006-001 to address multiple remote and local Mac OS X vulnerabilities.
Apple has also released updates to address these issues. Details of the fixes are
available via the PHP web site (www.php.net). PHP ships with Mac OS
X but is disabled by default.
automount
CVE-ID: CVE-2006-0384
Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X
v10.4.5, Mac OS X Server v10.4.5
Impact: Malicious network servers may cause a denial of service or
arbitrary code execution
Description: File servers on the local network may be able to cause
Mac OS X systems to mount file systems with reserved names. This
could cause the systems to become unresponsive, or possibly allow
arbitrary code delivered from the file servers to run on the target
system.
BOM
CVE-ID: CVE-2006-0391
Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X
v10.4.5, Mac OS X Server v10.4.5
Impact: Directory traversal may occur while unpacking archives with
BOM
Description: The BOM framework handles the unpacking of certain
types of archives. This framework is vulnerable to a directory
traversal attack that can allow archived files to be unpacked into
arbitrary locations that are writable by the current user. This
update addresses the issue by properly sanitizing those paths.
Credit to Stephane Kardas of CERTA for reporting this issue.
Directory Services
CVE-ID: CVE-2005-2713, CVE-2005-2714
Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X
v10.4.5, Mac OS X Server v10.4.5
Impact: Malicious local users may create and manipulate files as
root
Description: The passwd program is vulnerable to temporary file
attacks. This could lead to privilege elevation. This update
addresses the issue by anticipating a hostile environment and by
creating temporary files securely. Credit to Ilja van Sprundel of
Suresec LTD, vade79, and iDefense (idefense.com) for reporting this
issue.
FileVault
CVE-ID: CVE-2006-0386
Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X
v10.4.5, Mac OS X Server v10.4.5
Impact: FileVault may permit access to files during when it is
first enabled
Description: User directories are mounted in an unsafe fashion when
a FileVault image is created. This update secures the method in
which a FileVault image is created. This update addresses the issues by
correctly handling the conditions that may cause crashes. Credit to
OUSPG from the University of Oulu, NISCC, and CERT-FI for
coordinating and reporting this issue.
LibSystem
CVE-ID: CVE-2005-3706
Available for: Mac OS X v10.4.5, Mac OS X Server v10.4.5
Impact: Attackers may cause crashes or arbitrary code execution
depending upon the application
Description: An attacker able to cause an application to make
requests for large amounts of memory may also be able to trigger a
heap buffer overflow. This could cause the targeted application to
crash or execute arbitrary code. This update addresses the issue by
correctly handling these memory requests. This issue does not
affect systems prior to Mac OS X v10.4. Credit to Neil Archibald of
Suresec LTD for reporting this issue. Certain techniques can be used
to disguise the file's type so that Download Validation is
bypassed. This update addresses the issue by presenting Download
Validation with the entire file, providing more information for
Download Validation to detect unknown or unsafe file types in
attachments.
perl
CVE-ID: CVE-2005-4217
Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9
Impact: Perl programs may fail to drop privileges
Description: When a perl program running as root attempts to switch
to another user ID, the operation may fail without notification to
the program. This may cause a program to continue to run with root
privileges, assuming they have been dropped. This can cause
security issues in third-party tools. This update addresses the
issue by preventing such applications from continuing if the
operation fails. This issue does not affect Mac OS X v10.4 or later
systems. Credit to Jason Self for reporting this issue.
rsync
CVE-ID: CVE-2005-3712
Available for: Mac OS X v10.4.5, Mac OS X Server v10.4.5
Impact: Authenticated users may cause an rsync server to crash or
execute arbitrary code
Description: A heap-based buffer overflow may be triggered when the
rsync server is used with the flag that allows extended attributes
to be transferred. It may be possible for a malicious user with
access to an rsync server to cause denial of service or code
execution. This update addresses the problem by ensuring that the
destination buffer is large enough to hold the extended attributes.
This issue does not affect systems prior to Mac OS X v10.4. Credit
to Jan-Derk Bakker for reporting this issue.
Safari
CVE-ID: CVE-2005-4504
Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X
v10.4.5, Mac OS X Server v10.4.5
Impact: Viewing a maliciously-crafted web page may result in
arbitrary code execution
Description: A heap-based buffer overflow in WebKit's handling of
certain HTML could allow a malicious web site to cause a crash or
execute arbitrary code as the user viewing the site. This update
addresses the issue by preventing the condition causing the

The weakness is caused due to an error in the KHTMLParser when
parsing certain malformed HTML documents. This can be exploited to
crash an application that uses the parser via a specially crafted
HTML file. In certain cases, this may cause the system to become
unresponsive. Other applications that use the
parser may also be affected.
SOLUTION:
Do not open or follow links to HTML files from non-trusted sources.

Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X
v10.4.5, Mac OS X Server v10.4.5
Impact: Directory traversal may occur while unpacking archives with
BOM
Description: The BOM framework handles the unpacking of certain
types of archives. This framework is vulnerable to a directory
traversal attack that can allow archived files to be unpacked into
arbitrary locations that are writable by the current user. This
update addresses the issue by properly sanitizing those paths.
Credit to Stephane Kardas of CERTA for reporting this issue.
Directory Services
CVE-ID: CVE-2005-2713, CVE-2005-2714
Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X
v10.4.5, Mac OS X Server v10.4.5

LibSystem
CVE-ID: CVE-2005-3706
Available for: Mac OS X v10.4.5, Mac OS X Server v10.4.5
Impact: Attackers may cause crashes or arbitrary code execution
depending upon the application
Description: An attacker able to cause an application to make
requests for large amounts of memory may also be able to trigger a
heap buffer overflow. This could cause the targeted application to
crash or execute arbitrary code. This update addresses the issue by
correctly handling these memory requests. This issue does not
affect systems prior to Mac OS X v10.4. Credit to Neil Archibald of
Suresec LTD for reporting this issue.
Mail
CVE-ID: CVE-2006-0395

Impact: Download Validation fails to warn about unsafe file types
Description: In Mac OS X v10.4 Tiger, when an email attachment is
double-clicked in Mail, Download Validation is used to warn the
user if the file type is not "safe". Certain techniques can be used
to disguise the file's type so that Download Validation is
bypassed. This update addresses the issue by presenting Download
Validation with the entire file, providing more information for
Download Validation to detect unknown or unsafe file types in
attachments.
perl
CVE-ID: CVE-2005-4217
Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9
Impact: Perl programs may fail to drop privileges
Description: When a perl program running as root attempts to switch
to another user ID, the operation may fail without notification to
the program. This may cause a program to continue to run with root
privileges, assuming they have been dropped. This can cause
security issues in third-party tools. This update addresses the
issue by preventing such applications from continuing if the
operation fails. This issue does not affect Mac OS X v10.4 or later
systems. Credit to Jason Self for reporting this issue.
rsync
CVE-ID: CVE-2005-3712
Available for: Mac OS X v10.4.5, Mac OS X Server v10.4.5
Impact: Authenticated users may cause an rsync server to crash or
execute arbitrary code
Description: A heap-based buffer overflow may be triggered when the
rsync server is used with the flag that allows extended attributes
to be transferred. It may be possible for a malicious user with
access to an rsync server to cause denial of service or code
execution. This update addresses the problem by ensuring that the
destination buffer is large enough to hold the extended attributes.
This issue does not affect systems prior to Mac OS X v10.4. Credit
to Jan-Derk Bakker for reporting this issue.
Safari
CVE-ID: CVE-2005-4504
Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X
v10.4.5, Mac OS X Server v10.4.5
Impact: Viewing a maliciously-crafted web page may result in
arbitrary code execution
Description: A heap-based buffer overflow in WebKit's handling of
certain HTML could allow a malicious web site to cause a crash or
execute arbitrary code as the user viewing the site. This update
addresses the issue by preventing the condition causing the
overflow. Credit to Suresec LTD for reporting this issue.
Safari
CVE-ID: CVE-2006-0387

v10.4.5, Mac OS X Server v10.4.5
Impact: Viewing a malicious web page may cause arbitrary code
execution
Description: By preparing a web page including specially-crafted
JavaScript, an attacker may trigger a stack buffer overflow that
could lead to arbitrary code execution with the privileges of the
user. This update addresses the issue by performing additional
bounds checking. An issue involving HTTP
redirection can cause the browser to access a local file, bypassing
certain restrictions. This update addresses the issue by preventing
cross-domain HTTP redirects.

automount
CVE-ID: CVE-2006-0384
Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X
v10.4.5, Mac OS X Server v10.4.5
Impact: Malicious network servers may cause a denial of service or
arbitrary code execution
Description: File servers on the local network may be able to cause
Mac OS X systems to mount file systems with reserved names. This
could cause the systems to become unresponsive, or possibly allow
arbitrary code delivered from the file servers to run on the target
system.
BOM
CVE-ID: CVE-2006-0391
Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X
v10.4.5, Mac OS X Server v10.4.5
Impact: Directory traversal may occur while unpacking archives with
BOM
Description: The BOM framework handles the unpacking of certain
types of archives. This framework is vulnerable to a directory
traversal attack that can allow archived files to be unpacked into
arbitrary locations that are writable by the current user. This
update addresses the issue by properly sanitizing those paths.
Credit to Stephane Kardas of CERTA for reporting this issue.
Directory Services
CVE-ID: CVE-2005-2713, CVE-2005-2714
Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X
v10.4.5, Mac OS X Server v10.4.5
Impact: Malicious local users may create and manipulate files as
root
Description: The passwd program is vulnerable to temporary file
attacks. This could lead to privilege elevation. This update
addresses the issue by anticipating a hostile environment and by
creating temporary files securely. Credit to Ilja van Sprundel of
Suresec LTD, vade79, and iDefense (idefense.com) for reporting this
issue. This update secures the method in
which a FileVault image is created. This update addresses the issues by
correctly handling the conditions that may cause crashes. Credit to
OUSPG from the University of Oulu, NISCC, and CERT-FI for
coordinating and reporting this issue.
LibSystem
CVE-ID: CVE-2005-3706
Available for: Mac OS X v10.4.5, Mac OS X Server v10.4.5
Impact: Attackers may cause crashes or arbitrary code execution
depending upon the application
Description: An attacker able to cause an application to make
requests for large amounts of memory may also be able to trigger a
heap buffer overflow. This could cause the targeted application to
crash or execute arbitrary code. This update addresses the issue by
correctly handling these memory requests. This issue does not
affect systems prior to Mac OS X v10.4. Credit to Neil Archibald of
Suresec LTD for reporting this issue.
Mail
CVE-ID: CVE-2006-0395
Available for: Mac OS X v10.4.5, Mac OS X Server v10.4.5
Impact: Download Validation fails to warn about unsafe file types
Description: In Mac OS X v10.4 Tiger, when an email attachment is
double-clicked in Mail, Download Validation is used to warn the
user if the file type is not "safe". Certain techniques can be used
to disguise the file's type so that Download Validation is
bypassed. This update addresses the issue by presenting Download
Validation with the entire file, providing more information for
Download Validation to detect unknown or unsafe file types in
attachments.
perl
CVE-ID: CVE-2005-4217
Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9
Impact: Perl programs may fail to drop privileges
Description: When a perl program running as root attempts to switch
to another user ID, the operation may fail without notification to
the program. This may cause a program to continue to run with root
privileges, assuming they have been dropped. This can cause
security issues in third-party tools. This update addresses the
issue by preventing such applications from continuing if the
operation fails. This issue does not affect Mac OS X v10.4 or later
systems. Credit to Jason Self for reporting this issue.
rsync
CVE-ID: CVE-2005-3712
Available for: Mac OS X v10.4.5, Mac OS X Server v10.4.5
Impact: Authenticated users may cause an rsync server to crash or
execute arbitrary code
Description: A heap-based buffer overflow may be triggered when the
rsync server is used with the flag that allows extended attributes
to be transferred. It may be possible for a malicious user with
access to an rsync server to cause denial of service or code
execution. This update addresses the problem by ensuring that the
destination buffer is large enough to hold the extended attributes.
This issue does not affect systems prior to Mac OS X v10.4. Credit
to Jan-Derk Bakker for reporting this issue.
Safari
CVE-ID: CVE-2005-4504
Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X
v10.4.5, Mac OS X Server v10.4.5
Impact: Viewing a maliciously-crafted web page may result in
arbitrary code execution
Description: A heap-based buffer overflow in WebKit's handling of
certain HTML could allow a malicious web site to cause a crash or
execute arbitrary code as the user viewing the site. This update
addresses the issue by preventing the condition causing the
overflow. Credit to Suresec LTD for reporting this issue.
Safari
CVE-ID: CVE-2006-0387
Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X
v10.4.5, Mac OS X Server v10.4.5
Impact: Viewing a malicious web page may cause arbitrary code
execution
Description: By preparing a web page including specially-crafted
JavaScript, an attacker may trigger a stack buffer overflow that
could lead to arbitrary code execution with the privileges of the
user. This update addresses the issue by performing additional
bounds checking. An issue involving HTTP
redirection can cause the browser to access a local file, bypassing
certain restrictions. This update addresses the issue by preventing
cross-domain HTTP redirects.
Safari, LaunchServices
CVE-ID: CVE-2006-0394
Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X
v10.4.5, Mac OS X Server v10.4.5
Impact: Viewing a malicious web site may result in arbitrary code
execution
Description: It is possible to construct a file which appears to be
a safe file type, such as an image or movie, but is actually an
application. When the "Open `safe' files after downloading" option
is enabled in Safari's General preferences, visiting a malicious
web site may result in the automatic download and execution of such
a file. A proof-of-concept has been detected on public web sites
that demonstrates the automatic execution of shell scripts.
Syndication
CVE-ID: CVE-2006-0389
Available for: Mac OS X v10.4.5, Mac OS X Server v10.4.5
Impact: Subscriptions to malicious RSS content can lead to
cross-site scripting
Description: Syndication (Safari RSS) may allow JavaScript code
embedded in feeds to run within the context of the RSS reader
document, allowing malicious feeds to circumvent Safari's security
model. This update addresses the issue by properly removing
JavaScript code from feeds. Syndication is only available in Mac OS
X v10.4 and later.
The following security enhancements are also included in this update:
FileVault: AES-128 encrypted FileVault disk images are now created
with more restrictive operating system permissions. Credit to Eric
Hall of DarkArt Consulting Services for reporting this issue.
iChat: A malicious application named Leap.A that attempts to
propagate using iChat has been detected.

Mail
CVE-ID: CVE-2006-0395
Available for: Mac OS X v10.4.5, Mac OS X Server v10.4.5
Impact: Download Validation fails to warn about unsafe file types
Description: In Mac OS X v10.4 Tiger, when an email attachment is
double-clicked in Mail, Download Validation is used to warn the
user if the file type is not "safe". Certain techniques can be used
to disguise the file's type so that Download Validation is
bypassed. This update addresses the issue by presenting Download
Validation with the entire file, providing more information for
Download Validation to detect unknown or unsafe file types in
attachments.
perl
CVE-ID: CVE-2005-4217
Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9
Impact: Perl programs may fail to drop privileges
Description: When a perl program running as root attempts to switch
to another user ID, the operation may fail without notification to
the program. This may cause a program to continue to run with root
privileges, assuming they have been dropped. This can cause
security issues in third-party tools. This update addresses the
issue by preventing such applications from continuing if the
operation fails. Credit to Jason Self for reporting this issue. It may be possible for a malicious user with
access to an rsync server to cause denial of service or code
execution. This update addresses the problem by ensuring that the
destination buffer is large enough to hold the extended attributes. Credit
to Jan-Derk Bakker for reporting this issue. This update
addresses the issue by preventing the condition causing the
overflow. Credit to Suresec LTD for reporting this issue. This update addresses the issue by performing additional
bounds checking. An issue involving HTTP
redirection can cause the browser to access a local file, bypassing
certain restrictions. This update addresses the issue by preventing
cross-domain HTTP redirects. When the "Open `safe' files after downloading" option
is enabled in Safari's General preferences, visiting a malicious
web site may result in the automatic download and execution of such
a file. A proof-of-concept has been detected on public web sites
that demonstrates the automatic execution of shell scripts.
Syndication
CVE-ID: CVE-2006-0389
Available for: Mac OS X v10.4.5, Mac OS X Server v10.4.5
Impact: Subscriptions to malicious RSS content can lead to
cross-site scripting

| VAR-200603-0277 | CVE-2006-0389 | Apple Safari WebKit component vulnerable to buffer overflow |
CVSS V2: 2.6 CVSS V3: - Severity: LOW |
Cross-site scripting (XSS) vulnerability in Syndication (Safari RSS) in Mac OS X 10.4 through 10.4.5 allows remote attackers to execute arbitrary JavaScript via unspecified vectors involving RSS feeds. Apple Safari is vulnerable to a stack-based buffer overflow. This may allow a remote attacker to execute arbitrary code on a vulnerable system. Apple has released Security Update 2006-001 to address multiple remote and local Mac OS X vulnerabilities.
Apple has also released updates to address these issues. There is a directory traversal vulnerability in the implementation of this framework, which allows an attacker to decompress files to any location writable by the current user. If the user is logged
on with administrative privileges, the attacker could take complete
control of an affected system. Solution
Since there is no known patch for this issue at this time, US-CERT is
recommending a workaround.
----------------------------------------------------------------------
2003: 2,700 advisories published
2004: 3,100 advisories published
2005: 4,600 advisories published
2006: 5,300 advisories published
How do you know which Secunia advisories are important to you?
The Secunia Vulnerability Intelligence Solutions allows you to filter
and structure all the information you need, so you can address issues
effectively. This can be exploited via a specially
crafted email containing an attachment of an ostensibly safe file type
(e.g. ".jpg") to execute arbitrary shell commands when the attachment
is double-clicked.
SOLUTION:
Do not open attachments from untrusted sources.
1) Various security issues exist in the PHP Apache module and
scripting environment.
For more information:
SA17371
2) An error in automount makes it possible for malicious file servers
to cause a vulnerable system to mount file systems with reserved
names, which can cause a DoS (Denial of Service) or potentially allow
arbitrary code execution.
3) An input validation error in the BOM framework when unpacking
certain archives can be exploited to cause files to be unpacked to
arbitrary locations via directory traversal attacks.
4) The "passwd" program creates temporary files insecurely, which can
be exploited via symlink attacks to create or overwrite arbitrary
files with "root" privileges.
5) User directories are insecurely mounted when a FileVault image is
created, which may allow unauthorised access to files.
6) An error in IPSec when handling certain error conditions can be
exploited to cause a DoS against VPN connections.
7) An error in the LibSystem component can be exploited by malicious
people to cause a heap-based buffer overflow via applications when
requesting large amounts of memory.
8) The "Download Validation" in the Mail component fails to warn
users about unsafe file types when an e-mail attachment is
double-clicked.
9) In certain cases a Perl program may fail to drop privileges.
For more information:
SA17922
10) A boundary error in rsync can be exploited by authenticated users
to cause a heap-based buffer overflow when it's allowed to transfer
extended attributes.
11) A boundary error in WebKit's handling of certain HTML can be
exploited to cause a heap-based buffer overflow.
12) A boundary error in Safari when parsing JavaScript can be
exploited to cause a stack-based buffer overflow and allows execution
of arbitrary code when a malicious web page including specially
crafted JavaScript is viewed.
13) An error in Safari's security model when handling HTTP
redirection can be exploited to execute JavaScript in the local
domain via a specially crafted web site.
14) An error in Safari / LaunchServices may cause a malicious
application to appear as a safe file type. This may cause a malicious
file to be executed automatically when the "Open safe files after
downloading" option is enabled.

APPLE-SA-2006-03-01 Security Update 2006-001
Security Update 2006-001 is now available and addresses the following
issues:
apache_mod_php
CVE-ID: CVE-2005-3319, CVE-2005-3353, CVE-2005-3391, CVE-2005-3392
Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9, Mac OS X
v10.4.5, Mac OS X Server v10.4.5
Impact: Multiple security issues in PHP 4.4
Description: PHP 4.4.1 fixes several security issues in the Apache
module and scripting environment. Details of the fixes are
available via the PHP web site (www.php.net). This framework is vulnerable to a directory
traversal attack that can allow archived files to be unpacked into
arbitrary locations that are writable by the current user. This
update addresses the issue by properly sanitizing those paths.
Credit to Stephane Kardas of CERTA for reporting this issue. This could lead to privilege elevation. This update
addresses the issue by anticipating a hostile environment and by
creating temporary files securely. Credit to Ilja van Sprundel of
Suresec LTD, vade79, and iDefense (idefense.com) for reporting this
issue. This update secures the method in
which a FileVault image is created. This update addresses the issues by
correctly handling the conditions that may cause crashes. Credit to
OUSPG from the University of Oulu, NISCC, and CERT-FI for
coordinating and reporting this issue. This update addresses the issue by
correctly handling these memory requests. Credit to Neil Archibald of
Suresec LTD for reporting this issue.
Mail
CVE-ID: CVE-2006-0395
Available for: Mac OS X v10.4.5, Mac OS X Server v10.4.5
Impact: Download Validation fails to warn about unsafe file types
Description: In Mac OS X v10.4 Tiger, when an email attachment is
double-clicked in Mail, Download Validation is used to warn the
user if the file type is not "safe". Certain techniques can be used
to disguise the file's type so that Download Validation is
bypassed. This update addresses the issue by presenting Download
Validation with the entire file, providing more information for
Download Validation to detect unknown or unsafe file types in
attachments.
perl
CVE-ID: CVE-2005-4217
Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9
Impact: Perl programs may fail to drop privileges
Description: When a perl program running as root attempts to switch
to another user ID, the operation may fail without notification to
the program. This may cause a program to continue to run with root
privileges, assuming they have been dropped. This can cause
security issues in third-party tools. This update addresses the
issue by preventing such applications from continuing if the
operation fails. Credit to Jason Self for reporting this issue.
rsync
CVE-ID: CVE-2005-3712
Available for: Mac OS X v10.4.5, Mac OS X Server v10.4.5
Impact: Authenticated users may cause an rsync server to crash or
execute arbitrary code
Description: A heap-based buffer overflow may be triggered when the
rsync server is used with the flag that allows extended attributes
to be transferred. It may be possible for a malicious user with
access to an rsync server to cause denial of service or code
execution. This update addresses the problem by ensuring that the
destination buffer is large enough to hold the extended attributes. Credit
to Jan-Derk Bakker for reporting this issue. This update
addresses the issue by preventing the condition causing the
overflow. Credit to Suresec LTD for reporting this issue. This update addresses the issue by performing additional
bounds checking. An issue involving HTTP
redirection can cause the browser to access a local file, bypassing
certain restrictions. This update addresses the issue by preventing
cross-domain HTTP redirects. When the "Open `safe' files after downloading" option
is enabled in Safari's General preferences, visiting a malicious
web site may result in the automatic download and execution of such
a file. A proof-of-concept has been detected on public web sites
that demonstrates the automatic execution of shell scripts.
Syndication
CVE-ID: CVE-2006-0389
Available for: Mac OS X v10.4.5, Mac OS X Server v10.4.5
Impact: Subscriptions to malicious RSS content can lead to
cross-site scripting
Description: Syndication (Safari RSS) may allow JavaScript code
embedded in feeds to run within the context of the RSS reader
document, allowing malicious feeds to circumvent Safari's security
model. This update addresses the issue by properly removing
JavaScript code from feeds.
The following security enhancements are also included in this update:
FileVault: AES-128 encrypted FileVault disk images are now created
with more restrictive operating system permissions. Credit to Eric
Hall of DarkArt Consulting Services for reporting this issue.
iChat: A malicious application named Leap.A that attempts to
propagate using iChat has been detected.

| VAR-200512-0633 | CVE-2005-2713 | Apple MacOS X BOMArchiveHelper Directory traversal vulnerability |
CVSS V2: 6.8 CVSS V3: - Severity: MEDIUM |
passwd in Directory Services in Mac OS X 10.3.x before 10.3.9 and 10.4.x before 10.4.5 allows local users to create arbitrary world-writable files as root by specifying an alternate file in the password database option.
Apple has also released updates to address these issues. Apple Mac OS X 'passwd' creates temporary files in an insecure manner. This could allow a local attacker to elevate their privileges.
These issues were originally described in BID 16907 Apple Mac OS X Security Update 2006-001 Multiple Vulnerabilities.
More information is available at the following link:
http://www.apple.com/macosx/
II.
The /usr/bin/passwd binary is a setuid application which allows users to
change their password. There are two related vulnerabilities. The passwd binary does not check that the user has
permissions to create a file in the location specified and does not set
the created file permissions. By setting the file creation mask to 0 a
user can create arbitrary files owned by root, with permissions which
allow any user to change the contents.
The second vulnerability exists in the insecure creation of temporary
files with predictable names. The temporary filename created by the
process is in the form /tmp/.pwtmp.<pid> where <pid> is the process id
of the passwd process. By creating a symbolic link to the target file,
and then changing the password, it is possible to put controllable
contents into the target file.
III.
In the case of the first vulnerability, a new file could be created in
the /etc directory, such as etc/rc.local_tuning, which is sourced if it
exists during the system start up process as the root user.
The second vulnerability would allow an attacker overwrite a file with
user controlled contents. This can be leveraged to provide privilege
escalation by, for example, creating a new /etc/sudoers file.
IV.
V. WORKAROUND
Remove the setuid bit from the /usr/bin/passwd binary by executing the
following command as root:
chmod -s /usr/bin/passwd
This workaround will prevent non-root users from being able to change
their password.
VI. CVE INFORMATION
The Common Vulnerabilities and Exposures (CVE) project has assigned the
following names to these issues:
CVE-2005-2713 - passwd file creation and permissions
CVE-2005-2714 - temporary file symlink problem

Impact: Viewing a malicious web page may cause arbitrary code
execution
Description: By preparing a web page including specially-crafted
JavaScript, an attacker may trigger a stack buffer overflow that
could lead to arbitrary code execution with the privileges of the
user. This update addresses the issue by performing additional
bounds checking. An issue involving HTTP
redirection can cause the browser to access a local file, bypassing
certain restrictions. This update addresses the issue by preventing
cross-domain HTTP redirects. When the "Open `safe' files after downloading" option
is enabled in Safari's General preferences, visiting a malicious
web site may result in the automatic download and execution of such
a file. A proof-of-concept has been detected on public web sites
that demonstrates the automatic execution of shell scripts.

| VAR-200512-0634 | CVE-2005-2714 | Apple MacOS X BOMArchiveHelper Directory traversal vulnerability |
CVSS V2: 6.8 CVSS V3: - Severity: MEDIUM |
passwd in Directory Services in Mac OS X 10.3.x before 10.3.9 and 10.4.x before 10.4.5 allows local users to overwrite arbitrary files via a symlink attack on the .pwtmp.[PID] temporary file.
Apple has also released updates to address these issues. This could allow a local attacker to elevate their privileges.
These issues were originally described in BID 16907 Apple Mac OS X Security Update 2006-001 Multiple Vulnerabilities.
More information is available at the following link:
http://www.apple.com/macosx/
II.
The /usr/bin/passwd binary is a setuid application which allows users to
change their password. There are two related vulnerabilities.
The first vulnerability occurs because the Mac OS X version of the
passwd utility accepts options specifying which password database to
operate on. The passwd binary does not check that the user has
permissions to create a file in the location specified and does not set
the created file permissions. By setting the file creation mask to 0 a
user can create arbitrary files owned by root, with permissions which
allow any user to change the contents.
The second vulnerability exists in the insecure creation of temporary
files with predictable names. The temporary filename created by the
process is in the form /tmp/.pwtmp.<pid> where <pid> is the process id
of the passwd process. By creating a symbolic link to the target file,
and then changing the password, it is possible to put controllable
contents into the target file.
III.
In the case of the first vulnerability, a new file could be created in
the /etc directory, such as etc/rc.local_tuning, which is sourced if it
exists during the system start up process as the root user.
The second vulnerability would allow an attacker overwrite a file with
user controlled contents. This can be leveraged to provide privilege
escalation by, for example, creating a new /etc/sudoers file.
IV.
V. WORKAROUND
Remove the setuid bit from the /usr/bin/passwd binary by executing the
following command as root:
chmod -s /usr/bin/passwd
This workaround will prevent non-root users from being able to change
their password.
VI. CVE INFORMATION
The Common Vulnerabilities and Exposures (CVE) project has assigned the
following names to these issues:
CVE-2005-2713 - passwd file creation and permissions
CVE-2005-2714 - temporary file symlink problem

v10.4.5, Mac OS X Server v10.4.5
Impact: Directory traversal may occur while unpacking archives with
BOM
Description: The BOM framework handles the unpacking of certain
types of archives. This framework is vulnerable to a directory
traversal attack that can allow archived files to be unpacked into
arbitrary locations that are writable by the current user. This
update addresses the issue by properly sanitizing those paths.
Credit to Stephane Kardas of CERTA for reporting this issue. This could lead to privilege elevation. This update
addresses the issue by anticipating a hostile environment and by
creating temporary files securely. Credit to Ilja van Sprundel of
Suresec LTD, vade79, and iDefense (idefense.com) for reporting this
issue. This update secures the method in
which a FileVault image is created. This update addresses the issues by
correctly handling the conditions that may cause crashes. Credit to
OUSPG from the University of Oulu, NISCC, and CERT-FI for
coordinating and reporting this issue.
LibSystem
CVE-ID: CVE-2005-3706
Available for: Mac OS X v10.4.5, Mac OS X Server v10.4.5
Impact: Attackers may cause crashes or arbitrary code execution
depending upon the application
Description: An attacker able to cause an application to make
requests for large amounts of memory may also be able to trigger a
heap buffer overflow. This could cause the targeted application to
crash or execute arbitrary code. This update addresses the issue by
correctly handling these memory requests. This issue does not
affect systems prior to Mac OS X v10.4. Credit to Neil Archibald of

Available for: Mac OS X v10.4.5, Mac OS X Server v10.4.5
Impact: Download Validation fails to warn about unsafe file types
Description: In Mac OS X v10.4 Tiger, when an email attachment is
double-clicked in Mail, Download Validation is used to warn the
user if the file type is not "safe". Certain techniques can be used
to disguise the file's type so that Download Validation is
bypassed. This update addresses the issue by presenting Download
Validation with the entire file, providing more information for
Download Validation to detect unknown or unsafe file types in
attachments.
perl
CVE-ID: CVE-2005-4217
Available for: Mac OS X v10.3.9, Mac OS X Server v10.3.9
Impact: Perl programs may fail to drop privileges
Description: When a perl program running as root attempts to switch
to another user ID, the operation may fail without notification to
the program. This may cause a program to continue to run with root
privileges, assuming they have been dropped. This can cause
security issues in third-party tools. This update addresses the
issue by preventing such applications from continuing if the
operation fails. This issue does not affect Mac OS X v10.4 or later
systems. Credit to Jason Self for reporting this issue. It may be possible for a malicious user with

Impact: Viewing a malicious web site may result in arbitrary code
execution
Description: It is possible to construct a file which appears to be
a safe file type, such as an image or movie, but is actually an
application. When the "Open `safe' files after downloading" option
is enabled in Safari's General preferences, visiting a malicious
web site may result in the automatic download and execution of such
a file. A proof-of-concept has been detected on public web sites
that demonstrates the automatic execution of shell scripts.
Syndication
CVE-ID: CVE-2006-0389
Available for: Mac OS X v10.4.5, Mac OS X Server v10.4.5
Impact: Subscriptions to malicious RSS content can lead to

CVSS V2: 7.5 CVSS V3: - Severity: HIGH |
Perl in Apple Mac OS X Server 10.3.9 does not properly drop privileges when using the "$<" variable to set uid, which allows attackers to gain privileges. Apple Mac OS X's Perl is susceptible to an insecure privilege-dropping weakness. This issue is due to Perl's failure to correctly drop privileges. Presumably, the cause of this issue is a flaw in Perl's compilation options.
This vulnerability may allow attackers that exploit latent vulnerabilities in Perl applications to gain elevated privileges, increasing the potential for damage. The exact impact of exploitation depends on the specific use and implementation of the privilege-dropping facilities in affected Perl applications.
Mac OS X version 10.3.9 is reported vulnerable to this issue. Other versions may also be affected.

| VAR-200511-0079 | CVE-2005-3635 |
SAP Web Application Server Multiple Cross-Site Scripting Vulnerabilities
Related entries in the VARIoT exploits database: VAR-E-200511-0203 |
CVSS V2: 4.3 CVSS V3: - Severity: MEDIUM |
Multiple cross-site scripting (XSS) vulnerabilities in SAP Web Application Server (WAS) 6.10 through 7.00 allow remote attackers to inject arbitrary web script or HTML via (1) the sap-syscmd in sap-syscmd and (2) the BspApplication field in the SYSTEM PUBLIC test application. These issues are due to a failure in the application to properly sanitize user-supplied input.
An attacker may leverage these issues to have arbitrary script code executed in the browser of an unsuspecting user in the context of the affected site. This may facilitate the theft of cookie-based authentication credentials as well as other attacks.
This issue only affects the BSP runtime of SAP WAS.
1) Input passed to the "sap-syscmd" parameter in "fameset.htm" and
the "BspApplication" field in the "SYSTEM PUBLIC" test application
isn't properly sanitised before being returned to the user.
Other versions may also be affected.
2) Input passed to the query string in pages generating error
messages isn't properly sanitised before being returned to the user. Prior versions may also be
affected.
3) The problem is that an absolute URL for an external site can be
specified in the "sapexiturl" parameter passed to "fameset.htm". This
can be exploited to trick users into visiting a malicious web site by
following a specially crafted link with a trusted hostname
redirecting to the malicious web site.
Other versions may also be affected. This can be exploited to
inject arbitrary HTTP headers, which will be included in the response
sent to the user.
Other versions may also be affected.
SOLUTION:
The vendor has reportedly provided a solution for the
vulnerabilities. Customers should contact the SAP's support for
further information.
