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.

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. SOLUTION: Apply Security Update 2006-001.

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 VIII.

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.

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. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 National Cyber Alert System Technical Cyber Security Alert TA06-053A Apple Mac OS X Safari Command Execution Vulnerability Original release date: February 22, 2006 Last revised: -- Source: US-CERT Systems Affected Apple Safari running on Mac OS X Overview A file type determination vulnerability in Apple Safari could allow a remote attacker to execute arbitrary commands on a vulnerable system.

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. Safari CVE-ID: CVE-2006-0388 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: Remote web sites can redirect to local resources, allowing JavaScript to execute in the local domain Description: Safari's security model prevents remote resources from causing redirection to local resources. 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.

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.

SAP Web Application Server (WebAS) Kernel before 7.0 allows remote attackers to inject arbitrary bytes into the HTTP response and obtain sensitive authentication information, or have other impacts, via a ";%20" followed by encoded HTTP headers. SAP Web Application Server is prone to an input-validation vulnerability that results in HTTP response-splitting attacks. This issue is due to a failure in the application to properly sanitize user-supplied input. A remote attacker may exploit this vulnerability to influence or misrepresent how web content is served, cached, or interpreted. This could aid in various attacks that attempt to entice client users into a false sense of trust. Some unspecified input passed in the URL isn't properly sanitised before being returned to the user. This can be exploited to manipulate the HTTP response sent to the user and may allow execution of arbitrary HTML and script code in a user's browser session in context of an affected site. The vulnerability has been reported in version 7.00 and prior. SOLUTION: The vendor has released fixes for the vulnerability. See SAP Note 908147 and 915084 for details.
