<background>
<p>
zip is a compression and file packaging utility.
</p>
</background>
<description>
<p>
zip does not check the resulting path length when doing recursive
folder compression.
</p>
</description>
<impact type="normal">
<p>
An attacker could exploit this by enticing another user or web
application to create an archive including a specially-crafted path
name, potentially resulting in the execution of arbitrary code with the
permissions of the user running zip.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All zip users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=app-arch/zip-2.3-r4&quot;</code>
</resolution>
