## Description

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.
