Descriptions

nsHTMLContentSink.cpp in Mozilla Firefox and Thunderbird 1.x before 1.5 and 1.0.x before 1.0.8, Mozilla Suite before 1.7.13, and SeaMonkey before 1.0 allows remote attackers to cause a denial of service (crash) and possibly execute arbitrary code via unknown vectors involving a "particular sequence of HTML tags" that leads to memory corruption.

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.

Several security related problems have been discovered in Mozilla Thunderbird. This advisory addresses those issues.
