Multiple vulnerabilities have been identified in Cisco ASA and PIX, which could be exploited by attackers or malicious users to gain knowledge of sensitive information or cause a denial of service.
The first issue is caused by an unspecified error when processing SIP data while SIP inspection is enabled, which could be exploited to cause a vulnerable device to reload.
The second vulnerability is caused by an unspecified error related to authentication processing, which could be exploited to cause a device configured to terminate client based VPN connections to reload.
The third issue is caused by an error when processing specially crafted SSL or HTTP packets, which could be exploited to cause a device configured to terminate client based VPN connections to reload.
The fourth weakness is caused by an unspecified error that could allow attackers to discover potentially sensitive information such as usernames and passwords by tricking a user to visit a rogue web server, reply to an e-mail, or interact with a service.
