Summary
libapache-session-ldap-perl vulnerability
Details

It was discovered that Apache::Session::LDAP incorrectly handled invalid X.509 certificates. If a user or an automated system were tricked into opening a specially crafted invalid X.509 certificate, a remote attacker could possibly use this issue to perform spoofing and obtain sensitive information.
