<synopsis>

Apache is configured a certain way.

<p>
Apache is the most popular Web server on the Internet. mod_ssl provides
Secure Sockets Layer encryption and authentication to Apache 1.3. Apache 2
contains the functionality of mod_ssl.

<description>
<p>
A bug in the function ssl_util_uuencode_binary in ssl_util.c may lead to a
remote buffer overflow on a server configured to use FakeBasicAuth that
will trust a client certificate with an issuing CA with a subject DN longer
than 6k.
</p>
</description>
<impact type="high">
<p>
Given the right server configuration, an attacker could cause a Denial of
Service or execute code as the user running Apache, usually
&quot;apache&quot;. It is thought to be impossible to exploit this to
execute code on the x86 platform, but the possibility for other platforms
is unknown. This does not preclude a DoS on x86 systems.
</p>
</impact>
<workaround>
<p>
A server should not be vulnerable if it is not configured to use
FakeBasicAuth and to trust a client CA with a long subject DN.
</p>
</workaround>
<resolution>
<p>
Apache 1.x users should upgrade to the latest version of mod_ssl:
</p>
<code>
# emerge sync
# emerge -pv ">=net-www/mod_ssl-2.8.18"
# emerge ">=net-www/mod_ssl-2.8.18"</code>
<p>
Apache 2.x users should upgrade to the latest version of Apache:
</p>
<code>
# emerge sync
# emerge -pv ">=www-servers/apache-2.0.49-r3"
# emerge ">=www-servers/apache-2.0.49-r3"</code>
