TITLE

Mac OS X of Download Validation Vulnerable to arbitrary code execution

DESCRIPTION

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 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. Users should use caution when opening files that are obtained from the network.

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.
