ZDI-08-077: Trillian AIM IMG Tag Parsing Stack Overflow Vulnerability


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 tooltip processing code for

Trillian. When creating a tooltip for an image, the application

generates an XML tag including a property containing the filename. This

data is then copied directly into a stack-based buffer without any

length verifications which can eventually lead to code execution with

the privileges of the client.

-- Vendor Response:

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

details can be found at:
