The Apache HTTP server is one of the most popular web servers on the
|
|
Internet. mod_ssl provides SSL v2/v3 and TLS v1 support for Apache 1.3
|
|
and is also included in Apache 2.

<p>
|
|
mod_ssl contains a security issue when "SSLVerifyClient optional" is
|
|
configured in the global virtual host configuration (CAN-2005-2700).
|
|
Also, Apache's httpd includes a PCRE library, which makes it vulnerable
|
|
to an integer overflow (CAN-2005-2491).
|
|

|
<impact type="normal">
|
|
<p>
|
|
Under a specific configuration, mod_ssl does not properly enforce the
|
|
client-based certificate authentication directive, "SSLVerifyClient
|
|
require", in a per-location context, which could be potentially used by
|
|
a remote attacker to bypass some restrictions. By creating a specially
|
|
crafted ".htaccess" file, a local attacker could possibly exploit
|
|
Apache's vulnerability, which would result in a local privilege
|
|
escalation.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.

<resolution>

|
|
All mod_ssl users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=net-www/mod_ssl-2.8.24"</code>
|
|
<p>
|
|
All Apache 2 users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=www-servers/apache-2.0.54-r15"</code>
