Mandriva Linux Security Advisory 2012-145 - 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. Security researcher Mariusz Mlynski reported that it is possible to shadow the location object using Object.defineProperty.
