Synopsis
=======

Buffer overflow vulnerabilities have been found in mpg123 which could lead to execution of arbitrary code.

Background
=========

mpg123 is a MPEG Audio Player.

Affected packages
================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-sound/mpg123 < 0.59s-r5 >= 0.59s-r5

Description
==========

Buffer overflow vulnerabilities in the getauthfromURL() and http_open() functions have been reported by Carlos Barros. Additionally, the Gentoo Linux Sound Team fixed additional boundary checks which were found to be lacking.

Impact
=====

By enticing a user to open a malicious playlist or URL or making use of a specially-crafted symlink, an attacker could possibly execute arbitrary code with the rights of the user running mpg123.

Workaround
=========

There is no known workaround at this time.

Resolution
=========

All mpg123 users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=media-sound/mpg123-0.59s-r5"
