Internet Sharing in Apple Mac OS X before 10.7.3 does not preserve the Wi-Fi configuration across software updates, which allows remote attackers to obtain sensitive information by leveraging the lack of a WEP password for a Wi-Fi network.

Use-after-free vulnerability in CoreText in Apple Mac OS X before 10.7.3 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted embedded font in a document.

Apple Type Services (ATS) in Apple Mac OS X before 10.7.3 does not properly manage memory for data-font files, which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted font that is accessed by Font Book.

Address Book in Apple Mac OS X before 10.7.3 automatically switches to unencrypted sessions upon failure of encrypted connections, which allows remote attackers to read CardDAV data by terminating an encrypted connection and then sniffing the network.

Mozilla Firefox 4.x through 9.0 and SeaMonkey before 2.7 on Linux and Mac OS X set weak permissions for Firefox Recovery Key.html, which might allow local users to read a Firefox Sync key via standard filesystem operations.

Heap-based buffer overflow in libxml2, as used in Google Chrome before 16.0.912.75, allows remote attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors.

Mozilla Firefox before 3.6.25 and Thunderbird before 3.1.17 on Mac OS X do not consider .jar files to be executable files, which allows user-assisted remote attackers to bypass intended access restrictions via a crafted file. NOTE: this vulnerability exists because of an incorrect fix for CVE-2011-2372 on Mac OS X.

Mozilla Firefox before 9.0, Thunderbird before 9.0, and SeaMonkey before 2.6 on Mac OS X do not properly handle certain DOM frame deletions by plugins, which allows remote attackers to cause a denial of service (incorrect pointer dereference and application crash) or possibly have unspecified other impact via a crafted web site.

Unspecified vulnerability in the PRC component in Adobe Reader and Acrobat 9.x before 9.4.7 on Windows, Adobe Reader and Acrobat 9.x through 9.4.6 on Mac OS X, Adobe Reader and Acrobat 10.x through 10.1.1 on Windows and Mac OS X, and Adobe Reader 9.x through 9.4.6 on UNIX allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) via unknown vectors, as exploited in the wild in December 2011.

Unspecified vulnerability in Adobe Flash Player 11.1.102.55 on Windows and Mac OS X allows remote attackers to execute arbitrary code via a crafted SWF file, as demonstrated by the second of two vulnerabilities exploited by the Intevydis vd_adobe_fp module in VulnDisco Step Ahead (SA). NOTE: as of 20111207, this disclosure has no actionable information. However, because the module author is a reliable researcher, the issue is being assigned a CVE identifier for tracking purposes.

Mozilla Firefox before 8.0 and Thunderbird before 8.0 on Mac OS X do not properly interact with the GPU memory behavior of a certain driver for Intel integrated GPUs, which allows remote attackers to bypass the Same Origin Policy and read image data via vectors related to WebGL textures.

The Private Browsing feature in Apple Safari before 5.1.1 on Mac OS X does not properly recognize the Always value of the Block Cookies setting, which makes it easier for remote web servers to track users via a cookie.

The SSL implementation in Apple Safari before 5.1.1 on Mac OS X before 10.7 accesses uninitialized memory during the processing of X.509 certificates, which allows remote web servers to execute arbitrary code via a crafted certificate.

Apple Safari before 5.1.1 on Mac OS X does not enforce an intended policy for file: URLs, which allows remote attackers to execute arbitrary code via a crafted web site.

QuickTime in Apple Mac OS X before 10.7.2 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted movie file.

libsecurity in Apple Mac OS X before 10.7.2 does not properly handle errors during processing of a nonstandard extension in a Certificate Revocation list (CRL), which allows remote attackers to execute arbitrary code or cause a denial of service (application crash) a crafted (1) web site or (2) e-mail message.

The User Documentation component in Apple Mac OS X through 10.6.8 uses http sessions for updates to App Store help information, which allows man-in-the-middle attackers to execute arbitrary code by spoofing the http server.

Buffer overflow in QuickTime in Apple Mac OS X before 10.7.2 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted FLIC movie file.
