Mozilla Firefox Tag Parsing Code Execution Vulnerability
------------------------------------------------------------------------
SUMMARY
<http://www.mozilla.com/firefox/> Mozilla Firefox is "a free, open
source, cross-platform, graphical web browser developed by the Mozilla
Corporation and hundreds of volunteers".
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.
DETAILS
Vulnerable Systems:
* Firefox versions 1.0 - 1.0.7
* Thunderbird versions 1.5 - 1.5.0.1
* Thunderbird versions 1.0 - 1.0.7
* SeaMonkey version 1.0
* Mozilla Suite versions 1.7 - 1.7.12
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.
