Zero Day Initiative Advisory 10-131 – This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Mozilla Firefox. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the implementation of XUL element’s “selection” attribute. There is an integer overflow when calculating the bounds of a new selection range. When calling adjustSelection on this manged range both ranges are deleted leaving a dangling reference. A remote attacker can exploit this vulnerability to execute arbitrary code under the context of the browser.
