Synopsis
========
A buffer overflow vulnerability in libsndfile might allow remote
attackers to execute arbitrary code.

Background
==========
libsndfile is a C library for reading and writing files containing
sampled sound.

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-libs/libsndfile < 1.0.19 >= 1.0.19

Description
===========
Alin Rad Pop from Secunia Research reported an integer overflow when
processing CAF description chunks, leading to a heap-based buffer
overflow.

Impact
======
A remote attacker could entice a user to open a specially crafted CAF
file, resulting in the remote execution of arbitrary code with the
privileges of the user running the application.

Workaround
==========
There is no known workaround at this time.

Resolution
==========
All libsndfile users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/libsndfile-1.0.19"=

References
