TITLE:
libsndfile CAF Processing Integer Overflow Vulnerability

SECUNIA ADVISORY ID:
SA33980

VERIFY ADVISORY:
http://secunia.com/advisories/33980/

DESCRIPTION:
Secunia Research has discovered a vulnerability in libsndfile, which
can be exploited by malicious people to compromise an application
using the library.

The vulnerability is caused due to an integer overflow error in the
processing of CAF description chunks. This can be exploited to cause
a heap-based buffer overflow by tricking the user into processing a
specially crafted CAF audio file.

Successful exploitation may allow execution of arbitrary code.

The vulnerability is confirmed in version 1.0.18. Prior versions may
also be affected.

SOLUTION:
Update to version 1.0.19.
