Gentoo Linux Security Advisory

Title: Snack: User-assisted execution of arbitrary code (GLSA 201309-04)
Severity: normal
Exploitable: remote
Date: September 11, 2013
Bug(s): #446822
ID: 201309-04

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: dev-tcltk/snack
Vulnerable: < 2.2.10-r5
Unaffected: >= 2.2.10-r5
Architectures: All supported architectures


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