Google Chrome 17.0.963.66 and earlier allows remote attackers to bypass the sandbox protection mechanism by leveraging access to a sandboxed process, as demonstrated by VUPEN during a Pwn2Own competition at CanSecWest 2012. NOTE: the primary affected product may be clarified later; it was not identified by the researcher, who reportedly stated "it really doesn't matter if it's third-party code."

Use-after-free vulnerability in Google Chrome 17.0.963.66 and earlier allows remote attackers to bypass the DEP and ASLR protection mechanisms, and execute arbitrary code, via unspecified vectors, as demonstrated by VUPEN during a Pwn2Own competition at CanSecWest 2012. NOTE: the primary affected product may be clarified later; it was not identified by the researcher, who reportedly stated "it really doesn't matter if it's third-party code."

Google V8, as used in Google Chrome before 17.0.963.83, allows remote attackers to cause a denial of service via vectors that trigger an invalid read operation.

Google Chrome before 17.0.963.83 allows remote attackers to bypass the Same Origin Policy via vectors involving a "magic iframe."

The browser native UI in Google Chrome before 17.0.963.83 does not require user confirmation before an unpacked extension installation, which allows user-assisted remote attackers to have an unspecified impact via a crafted extension.

The WebUI privilege implementation in Google Chrome before 17.0.963.83 does not properly perform isolation, which allows remote attackers to bypass intended access restrictions via unspecified vectors.

Use-after-free vulnerability in Google Chrome before 17.0.963.83 allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to block splitting.

The WebGL implementation in Google Chrome before 17.0.963.83 does not properly handle CANVAS elements, which allows remote attackers to cause a denial of service (memory corruption) or possibly have unspecified other impact via unknown vectors.

Use-after-free vulnerability in the Cascading Style Sheets (CSS) implementation in Google Chrome before 17.0.963.83 allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to the cross-fade function.

Use-after-free vulnerability in the Cascading Style Sheets (CSS) implementation in Google Chrome before 17.0.963.83 allows remote attackers to cause a denial of service or possibly have unspecified other impact via vectors related to the :first-letter pseudo-element.

Integer signedness error in the png_inflate function in pngrutil.c in libpng before 1.4.10beta01, as used in Google Chrome before 17.0.963.83 and other products, allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via a crafted PNG file, a different vulnerability than CVE-2011-3026.

The GPU process in Google Chrome before 17.0.963.79 allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption) by leveraging an error in the plug-in loading mechanism.

The extension subsystem in Google Chrome before 17.0.963.78 does not properly handle history navigation, which allows remote attackers to execute arbitrary code by leveraging a "Universal XSS (UXSS)" issue.
