CVE-2008-0555
Apache-SSL - Authentication Bypass via Malformed Distinguished Name in Client Certificate
Title source: llmDescription
The ExpandCert function in Apache-SSL before apache_1.3.41+ssl_1.59 does not properly handle (1) '/' and (2) '=' characters in a Distinguished Name (DN) in a client certificate, which might allow remote attackers to bypass authentication via a crafted DN that triggers overwriting of environment variables.
