Trillian AIM.DLL Long HTML Font Parameter Stack Overflow Vulnerability
Vulnerability Details
This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Trillian. User interaction is required to exploit this vulnerability in that the target must open a malicious image file.
The specific flaws exists during the parsing of messages with overly long attribute values within the FONT tag. The value for any attribute is copied into a stack based buffer via sprintf() which can result in a buffer overrun and can be subsequently leveraged to execute arbitrary code under the privileges of the logged in user. Exploitation may occur over the AIM network or via direct connections.
Additional Details
Trillian v3.1.10.0 has been released to address these vulnerabilities and is available at http://www.ceruleanstudios.com/downloads/
