<description>
<p>
Limin Wang has located a buffer overflow inside the put_words()
function in the abcm2ps code.
</p>
</description>
<impact type="normal">
<p>
A remote attacker could convince the victim to download a
specially-crafted ABC file. Upon execution, this file would trigger the
buffer overflow and lead to the execution of arbitrary code with the
permissions of the user running abcm2ps.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All abcm2ps users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=media-sound/abcm2ps-3.7.21&quot;</code>
</resolution>
