<p>Snack is a sound toolkit for creating multi-platform audio applications
with scripting languages.
<p>The GetWavHeader() function in jkSoundFile.c does not have boundary
checks when parsing format sub-chunks or unknown sub-chunks.
<impact type="normal">
<p>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.
<p>There is no known workaround at this time.</p>
<p>All Snack users should upgrade to the latest version:</p>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=dev-tcltk/snack-2.2.10-r5"
