Mandriva Linux Security Advisory 2013-165 - 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 Cody Crews reported a method to call a content level constructor that allows for this constructor to have chrome privileged access. This affects chrome object wrappers and allows for write actions on objects when only read actions should be allowed. This can lead to cross-site scripting attacks. Various other issues have also been addressed.
