7e2ba174ec10c01fce0c731b332c6252Ubuntu Security Notice 1548-2 - USN-1548-1 fixed vulnerabilities in Firefox. The new package caused a regression in Private Browsing which could leak sites visited to the browser cache. This update fixes the problem. Gary Kwong, Christian Holler, Jesse Ruderman, Steve Fink, Bob Clary, Andrew Sutherland, Jason Smith, John Schoenick, Vladimir Vukicevic and Daniel Holbert discovered memory safety issues affecting Firefox. If the user were tricked into opening a specially crafted page, an attacker could possibly exploit these to cause a denial of service via application crash, or potentially execute code with the privileges of the user invoking Firefox. Abhishek Arya discovered multiple use-after-free vulnerabilities. If the user were tricked into opening a specially crafted page, an attacker could exploit these to cause a denial of service via application crash, or potentially execute code with the privileges of the user invoking Firefox. Various other issues were also addressed.

139786f07550858f55d28618106168cfMandriva Linux Security Advisory 2012-147 - Mozilla developers identified and fixed several memory safety bugs in the browser engine used in Firefox and other Mozilla-based products. Some of these bugs showed evidence of memory corruption under certain circumstances, and we presume that with enough effort at least some of these could be exploited to run arbitrary code. In general these flaws cannot be exploited through email in the Thunderbird and SeaMonkey products because scripting is disabled, but are potentially a risk in browser or browser-like contexts in those products. Security researcher Abhishek Arya of Google Chrome Security Team discovered a series of use-after-free issues using the Address Sanitizer tool. Many of these issues are potentially exploitable, allowing for remote code execution. Security researcher Mariusz Mlynski reported that it is possible to shadow the location object using Object.defineProperty. This could be used to confuse the current location to plugins, allowing for possible cross-site scripting attacks. Various other vulnerabilities were also addressed.
