Mandriva Linux Security Advisory 2012-173 - 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. Security researcher Atte Kettunen from OUSPG used the Address Sanitizer tool to discover a buffer overflow while rendering GIF format images. This issue is potentially exploitable and could lead to arbitrary code execution. Various other issues were also addressed.
