Mandriva 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.
