ZDI-08-079: Trillian AIM Plugin Malformed XML Tag Heap Overflow



December 4, 2008

-- Affected Vendors:

Cerulean Studios

-- Affected Products:

Cerulean Studios Trillian

-- Vulnerability Details:

This vulnerability allows remote attackers to execute arbitrary code on

vulnerable installations of Cerulean Studios Trillian. Authentication is

not required to exploit this vulnerability.

The specific flaw exists within the XML processing code for Trillian.

When parsing a malformed XML tag, the application does not allocate

enough space for it's contents. During copying of this to the newly

allocated buffer, the application will overwrite heap structures with

attacker-supplied data that can then be leveraged to achieve code

execution with the privileges of the application.

Cerulean Studios has issued an update to correct this vulnerability. More
