modules/webaudio/BiquadDSPKernel.cpp in the Web Audio API implementation in Blink, as used in Google Chrome before 37.0.2062.94, does not properly consider concurrent threads during attempts to update biquad filter coefficients, which allows remote attackers to cause a denial of service (read of uninitialized memory) via crafted API calls.

Affected: Ubuntu:14.04:LTS: oxide-qt

A use-after-free was discovered in the SVG implementation in Blink. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via renderer crash, or execute arbitrary code with the privileges of the sandboxed render process. (CVE-2014-3168)

A use-after-free was discovered in the DOM implementation in Blink. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via renderer crash, or execute arbitrary code with the privileges of the sandboxed render process. (CVE-2014-3169)

A use-after-free was discovered in V8. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service via renderer crash, or execute arbitrary code with the privileges of the sandboxed render process. (CVE-2014-3171)

It was discovered that WebGL clear calls did not interact properly with the state of a draw buffer. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service. (CVE-2014-3173)

A threading issue was discovered in the Web Audio API during attempts to update biquad filter coefficients. If a user were tricked in to opening a specially crafted website, an attacker could potentially exploit this to cause a denial of service. (CVE-2014-3174)

Multiple security issues were discovered i…
