DESCRIPTION:
Sergio Alvarez has reported a vulnerability in BitDefender
Anti-Virus, which can be exploited by malicious people to compromise
a vulnerable system.

The vulnerability is caused due to an integer overflow within the
AntiVirus engine when parsing certain packed PE files. This can be
exploited to cause a heap-based buffer overflow via a specially
crafted PE file.

Successful exploitation may allow execution of arbitrary code.

SOLUTION:
Update to the latest version.

PROVIDED AND/OR DISCOVERED BY:
Sergio Alvarez, n.runs AG.
