Mandriva Linux Security Advisory 2012-163 - 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 it is presumed that with enough effort at least some of these could be exploited to run arbitrary code. Various other issues have been addressed. The mozilla firefox packages has been upgraded to the latest version which is unaffected by these security flaws.
