Date:	12/11/2016

ID:	201612-29

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	Architecture(s)
media-libs/libmms	< 0.6.4	>= 0.6.4	All supported architectures

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"
