Vulnerability Assessment Details

[GLSA-200509-12] Apache, mod_ssl: Multiple vulnerabilities

Vulnerability Assessment Summary
Apache, mod_ssl: Multiple vulnerabilities

Detailed Explanation for this Vulnerability Assessment
The remote host is affected by the vulnerability described in GLSA-200509-12
(Apache, mod_ssl: Multiple vulnerabilities)


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

Impact

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.

Workaround

There is no known workaround at this time.

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