Synopsis
========

An error in mpg123 might allow for the execution of arbitrary code.

Background
==========

mpg123 is a realtime MPEG 1.0/2.0/2.5 audio player for layers 1, 2 and

Description
===========

The vendor reported a signedness error in the store_id3_text() function
in id3.c, allowing for out-of-bounds memory access.

Impact
======

A remote attacker could entice a user to open an MPEG-1 Audio Layer 3
(MP3) file containing a specially crafted ID3 tag, possibly resulting
