-- Affected Vendors:
Cerulean Studios

-- Affected Products:
Cerulean Studios Trillian

-- Vulnerability Details:
This vulnerability allows remote attackers to potentially 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 specially formulated xml, the application will corrupt an
internal data structure. Whilst deallocating this data structure, the
application can be tricked into freeing a single allocated chunk
multiple times, which can potentially lead to code execution.

-- Vendor Response:
Trillian has issued an update to correct this vulnerability. More
