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"
