SoX: Multiple buffer overflows

Background

SoX is a command line utility that can convert various formats of computer audio files in to other formats.

Description

Ulf Harnhammar discovered two buffer overflows in the sox and play commands when handling WAV files with specially crafted header fields.

Impact

By enticing a user to play or convert a specially crafted WAV file an attacker could execute arbitrary code with the permissions of the user running SoX.

Workaround

There is no known workaround at this time. All users are encouraged to upgrade to the latest available version of SoX.

Resolution

All SoX users should upgrade to the latest version:

 # emerge sync
 
 # emerge -pv ">=media-sound/sox-12.17.4-r2"
 # emerge ">=media-sound/sox-12.17.4-r2"
