Synopsis
========
A heap-based buffer overflow vulnerability in libmms might allow remote
attackers to execute arbitrary code.

Background
==========
libmms is a library for downloading (streaming) media files using the
mmst and mmsh protocols.

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-libs/libmms < 0.6.4 >= 0.6.4

Description
===========
A heap-based buffer overflow was discovered in the get_answer function
within mmsh.c of libmms.

Impact
======
A remote attacker might send a specially crafted MMS over HTTP (MMSH)
response, possibly resulting in the remote execution of arbitrary code
with the privileges of the process.

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

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

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-libs/libmms-0.6.4"

References
