Synopsis
========
A heap overflow in mpg123 was discovered, which could result in the
execution of arbitrary code.
Background
==========
mpg123 is a real time audio player designed for the MPEG format.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 media-sound/mpg123 lt; 0.59s-r11 gt;= 0.59s-r11
Description
===========
In httpdget.c, a variable is assigned to the heap, and is supposed to
receive a smaller allocation. As this variable was not terminated
properly, strncpy() will overwrite the data assigned next in memory.
Impact
======
By enticing a user to visit a malicious URL, 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 update to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose "gt;=media-sound/mpg123-0.59s-r11"
Availability
============
This GLSA and any updates to it are available for viewing at
