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