Synopsis
========
A buffer overflow in Snack could result in execution of arbitrary code
or Denial of Service.

Background
==========
Snack is a sound toolkit for creating multi-platform audio applications
with scripting languages.

Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-tcltk/snack < 2.2.10-r5 >= 2.2.10-r5

Description
===========
The GetWavHeader() function in jkSoundFile.c does not have boundary
checks when parsing format sub-chunks or unknown sub-chunks.

Impact
======
A remote attacker could entice a user to open a specially crafted WAV
file with an application using Snack, possibly resulting in execution
of arbitrary code or a Denial of Service condition.

Workaround
==========
There is no known workaround at this time.

Resolution
==========
All Snack users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose ">=dev-tcltk/snack-2.2.10-r5"

References
==========
