TITLE

Apple Mac OS X CoreFoundation Buffer overflow vulnerability

DESCRIPTION

Integer underflow in CoreFoundation in Apple Mac OS X 10.3.9 and 10.4.6 allows context-dependent attackers to execute arbitrary code via unspecified vectors involving conversions from string to file system representation within (1) CFStringGetFileSystemRepresentation or (2) getFileSystemRepresentation:maxLength:withPath in NSFileManager, and possibly other similar API functions. Apple Mac OS X is reported prone to multiple security vulnerabilities. These issue affect Mac OS X in the following applications or modules: - AppKit - ImageIO - BOM - CFNetwork - ClamAV - CoreFoundation - CoreGraphics - Finder - FTPServer - Flash Player - ImageIO - Keychain - LaunchServices - libcurl - Mail - MySQL Manager - Preview - QuickDraw - QuickTime Streaming Server - Ruby - Safari A remote attacker may exploit these issues to execute arbitrary code, trigger a denial-of-service condition, gain access to potentially sensitive information, or overwrite files. Other attacks may also be possible. Apple Mac OS X 10.4.6 and prior are reported vulnerable to these issues. 1) An error in the AppKit framework allows an application to read characters entered into secure text field in the same window session. 2) Errors in the AppKit and ImageIO framework when processing GIF and TIFF images can be exploited to crash an application or potentially execute arbitrary code. For more information: SA19686 3) A boundary error within the BOM component when expanding archives can be exploited to crash an application or potentially execute arbitrary code. For more information: SA19686 4) An input validation error in the BOM component when expanding archives can be exploited to cause files to be written to arbitrary locations outside the specified directory via directory traversal attacks. 5) An integer overflow error in the CFNetwork component when handling chunked transfer encoding may allow execution of arbitrary code if a user is tricked into visiting a malicious web site. 6) Errors in ClamAV when processing specially crafted email messages may allow execution of arbitrary code. For more information: SA19534 7) An error in the CoreFoundation component allows dynamic libraries to load and execute when a bundle is registered. This can be exploited to execute arbitrary code if an untrusted bundle is registered. 9) An error in the CoreGraphics component allows an application in the same window session to read characters entered into secure text field when "Enable access for assistive devices" is enabled. 10) An error in Finder within the handling of Internet Location items makes it possible to specify a different Internet Location type than the actual URL scheme used. This may allow execution of arbitrary code when launching an Internet Location item. 11) Boundary errors in the FTPServer component when handling path names can be exploited to malicious users to cause a buffer overflow, which may allow execution of arbitrary code. 12) Various errors in the Flash Player makes it possible to compromise a user's system via specially crafted Flash files. For more information: SA17430 SA19218 13) An integer overflow error in the ImageIO framework when processing JPEG images can be exploited to crash an application or potentially execute arbitrary code. 14) An error in the Keychain component allows an application to use Keychain items even when the Keychain is locked. This requires that the application has obtained a reference to a Keychain item before the Keychain was locked. 15) An error in the LaunchServices component when processing long filename extensions may allow bypassing of the Download Validation functionality. 16) Boundary errors in the libcurl URL handling may allow execution of arbitrary code. For more information: SA17907 17) An integer overflow error in the Mail component may allow execution of arbitrary code when viewing a specially crafted email message with MacMIME encapsulated attachments. 18) An error in the Mail component when handling invalid colour information in enriched text email messages may allow execution of arbitrary code. 19) An design error in MySQL Manager makes it possible to access the MySQL database with an empty password as the MySQL password supplying during initial setup is not used. 20) A boundary error in the Preview component may allow execution of arbitrary code via a stack-based buffer overflow when navigating a specially crafted directory hierarchy. 21) Two boundary errors in the QuickDraw component when processing of PICT images can be exploited to either cause a stack-based via a PICT image with specially crafted font information or a heap-based buffer overflow via a PICT image with specially crafted image data. This can be exploited to crash an application and potentially execute arbitrary code. 22) A NULL pointer dereference error in QuickTime Streaming Server when processing QuickTime movies with a missing track can be exploited to crash the application. 23) A boundary error in QuickTime Streaming Server when processing RTSP requests can be exploited to crash the application or potentially execute arbitrary code. 24) An error in Ruby can be exploited to bypass safe level restrictions. For more information: SA16904 25) An error in Safari when handling archives with symbolic links may place the symbolic links on a user's desktop. This requires that the "Open 'safe' files after downloading" option is enabled.
