<impact type="low">
<p>
A remote attacker could send a specially crafted URL to the vulnerable
Tomcat server, possibly resulting in a directory traversal and read
access to arbitrary files with the privileges of the user running
Tomcat. Note that this vulnerability can only be exploited when using
apache proxy modules like mod_proxy, mod_rewrite or mod_jk.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All Tomcat users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=www-servers/tomcat-5.5.22&quot;</code>
</resolution>
