A buffer overflow in Snack could result in execution of arbitrary code or Denial of Service.
|Package||dev-tcltk/snack on all architectures|
|Affected versions||< 2.2.10-r5|
|Unaffected versions||>= 2.2.10-r5|
Snack is a sound toolkit for creating multi-platform audio applications with scripting languages.
The GetWavHeader() function in jkSoundFile.c does not have boundary checks when parsing format sub-chunks or unknown sub-chunks.
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.
There is no known workaround at this time.
All Snack users should upgrade to the latest version:
# emerge --sync # emerge --ask --oneshot --verbose ">=dev-tcltk/snack-2.2.10-r5"
