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"
