Technical Description

Two vulnerabilities have been identified in Trillian, which could be exploited by remote attackers to take complete control of an affected system.

The first issue is caused by an input validation error when processing the "ini" parameter supplied via "aim://" URIs, which could be exploited by remote attackers to create arbitrary files on an affected system by tricking a user into visiting a specially crafted web page.

The second vulnerability is caused by a buffer overflow error in the "aim.dll" module when processing an overly long "aim://" URI, which could be exploited by attackers to crash an affected application or execute arbitrary code by tricking a user into visiting a malicious web page.
