Multiple vulnerabilities have been identified in Cisco PIX and ASA, which could be exploited by attackers to bypass security checks or cause a denial of service.
The first issue is caused by an error when using a Lightweight Directory Access Protocol (LDAP) authentication server, which could be exploited by attackers to gain unauthorized access to a vulnerable device internal resources.
The second vulnerability is caused by an error when terminating Virtual Private Networks (VPN) while the tunnel group is configured with password expiry, which could be exploited by an attacker who knows the group name and group password to cause a denial of service.
The third issue is caused by a race condition within the SSL VPN HTTP server when processing non-standard SSL sessions, which could be exploited by attackers to reload a vulnerable device, creating a denial of service condition.
