Mandriva Linux Security Advisory 2012-146 - Mozilla developers identified and fixed several memory safety bugs in the browser engine used in Firefox and other Mozilla-based products.

Security researcher Abhishek Arya of Google Chrome Security Team discovered a series of use-after-free issues using the Address Sanitizer tool.
