VERIFY ADVISORY:
http://secunia.com/advisories/20921/

Highly critical

DESCRIPTION:
infamous41md has reported a vulnerability in libwmf, which
potentially can be exploited by malicious people to compromise an
application using the vulnerable library.

The vulnerability is caused due to an integer overflow error when
allocating memory based on a value taken directly from a WMF file
without performing any checks. This can be exploited to cause a
heap-based buffer overflow when a specially crafted WMF file is
processed.

Successful exploitation may allow execution of arbitrary code.

The vulnerability has been reported in version 0.2.8.4. Other
versions may also be affected.

SOLUTION:
Do not open untrusted WMF files in applications using the vulnerable
library.
