<title>Apache: buffer overflows and a possible information disclosure</title>
<synopsis>
Multiple stack-based buffer overflows in mod_alias and mod_rewrite can allow
execution of arbitrary code and cause a denial of service, and a bug in the
way mod_cgid handles CGI redirect paths could result in CGI output going to
the wrong client.

The Apache HTTP Server is one of the most popular web servers on the
Internet.

<p>
Multiple stack-based buffer overflows in mod_alias and mod_rewrite allow
attackers who can create or edit configuration files including .htaccess
files, to cause a denial of service and execute arbitrary code via a regular
expression containing more than 9 captures, and a bug in the way mod_cgid
handles CGI redirect paths could result in CGI output going to the wrong
client when a threaded MPM is used, resulting in an information disclosure.
</p>
</description>
<impact type="normal">
<p>
An attacker may cause a denial of service or execute arbitrary code with the
privileges of the user that is running apache.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
It is recommended that all Gentoo Linux users who are running
net-misc/apache 2.x upgrade:
</p>
<code>
# emerge sync
# emerge -pv '&gt;=www-servers/apache-2.0.48'
# emerge '&gt;=www-servers/apache-2.0.48'
# emerge clean
# /etc/init.d/apache2 restart</code>
<p>
Please remember to update your config files in /etc/apache2 as --datadir has
been changed to /var/www/localhost.
</p>
