GLSA 201309-04: Snack: User-assisted execution of arbitrary code

Severity:normal
Title:Snack: User-assisted execution of arbitrary code
Date:09/11/2013
Bugs: #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 Vulnerable Unaffected Architecture(s)
dev-tcltk/snack < 2.2.10-r5 >= 2.2.10-r5 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:

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