VULNERABILITY DETAILS

This vulnerability allows attackers to execute arbitrary code on vulnerable installations of the Mozilla/Firefox web browser and Thunderbird e-mail client. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious e-mail.

The specific flaw exists within nsHTMLContentSink.cpp, during the parsing of HTML tags as they appear in a specific order. The flaw results in a memory corruption that leads to an attacker controlled function pointer dereference from the stack and eventually execution of arbitrary code.
