DESCRIPTION:
ProTeuS has discovered a vulnerability in BitDefender Antivirus,
which can be exploited by malicious people to cause a DoS (Denial of
Service) or to potentially compromise a vulnerable system.

The vulnerability is caused due to a boundary error in the "pdf.xmd"
module when processing data encoded using e.g. the "FlateDecode" and
"ASCIIHexDecode" filters. This can be exploited to cause a memory
corruption via a specially crafted PDF file.

Successful exploitation may allow execution of arbitrary code.

The vulnerability is confirmed in BitDefender Free Edition 10 updated
