Advisory ID: ZSL-2012-5103
Type: Local/Remote
Impact: System Access, DoS
Risk: (4/5)
Release Date: 28.08.2012

Summary

Express Burn is a program that allows you to create and copy many kinds of disc media, including Audio (audio CDs / .mp3 CDs), Video (DVDs), and Data (CDs / DVDs / Blu-ray).

Description

The vulnerability is caused due to a boundary error in the processing of a project file, which can be exploited to cause a unicode buffer overflow when a user opens e.g. a specially crafted .EBP file. Successful exploitation could allow execution of arbitrary code on the affected machine.
