The PDF functionality in Google Chrome before 21.0.1180.57 on Mac OS X and Linux, and before 21.0.1180.60 on Windows and Chrome Frame, does not properly handle object linkage, which allows remote attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact via a crafted document.

Multiple integer overflows in the PDF functionality in Google Chrome before 21.0.1180.57 on Mac OS X and Linux, and before 21.0.1180.60 on Windows and Chrome Frame, allow remote attackers to cause a denial of service or possibly have unspecified other impact via a crafted document.

Multiple unspecified vulnerabilities in the PDF functionality in Google Chrome before 21.0.1180.57 on Mac OS X and Linux, and before 21.0.1180.60 on Windows and Chrome Frame, allow remote attackers to have an unknown impact via a crafted document.

Off-by-one error in the GIF decoder in Google Chrome before 21.0.1180.57 on Mac OS X and Linux, and before 21.0.1180.60 on Windows and Chrome Frame, allows remote attackers to cause a denial of service (out-of-bounds read) via a crafted image.

The drag-and-drop implementation in Google Chrome before 21.0.1180.57 on Mac OS X and Linux, and before 21.0.1180.60 on Windows and Chrome Frame, allows user-assisted remote attackers to bypass intended file access restrictions via a crafted web site.

Google Chrome before 21.0.1180.57 on Mac OS X and Linux, and before 21.0.1180.60 on Windows and Chrome Frame, does not request user confirmation before continuing a large series of downloads, which allows user-assisted remote attackers to cause a denial of service (resource consumption) via a crafted web site.

Memory leak in the poolGrow function in expat/lib/xmlparse.c in expat before 2.1.0 allows context-dependent attackers to cause a denial of service (memory consumption) via a large number of crafted XML files that cause improperly-handled reallocation failures when expanding entities.

Use-after-free vulnerability in the UI in Google Chrome before 20.0.1132.43 on Mac OS X allows attackers to cause a denial of service or possibly have unspecified other impact via unknown vectors.

The VPN downloader implementation in the WebLaunch feature in Cisco AnyConnect Secure Mobility Client 2.x before 2.5 MR6 on Windows, and 2.x before 2.5 MR6 and 3.x before 3.0 MR8 on Mac OS X and Linux, does not properly validate binaries that are received by the downloader process, which allows remote attackers to execute arbitrary code via vectors involving (1) ActiveX or (2) Java components, aka Bug ID CSCtw47523.

Unspecified vulnerability in Opera before 12.00 on Mac OS X has unknown impact and attack vectors, related to a "moderate severity issue."

Time Machine in Apple Mac OS X before 10.7.4 does not require continued use of SRP-based authentication after this authentication method is first used, which allows remote attackers to read Time Capsule credentials by spoofing the backup volume.

Integer overflow in the Security Framework in Apple Mac OS X before 10.7.4 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via crafted input.

Buffer underflow in QuickTime in Apple Mac OS X before 10.7.4 allows remote attackers to execute arbitrary code or cause a denial of service (application crash) via a crafted MPEG file.
