Description

The remote Cisco ASA is missing a security patch and may be vulnerable to the following issues :

  • Multiple DoS vulnerabilities in the SunRPC inspection engine that can be triggered by sending unspecified UDP packets. (CVE-2010-1578, CVE-2010-1579, CVE-2010-1580)

  • Multiple TLS DoS vulnerabilities. Devices configured for SSL VPN, TLS Proxy for Encrypted Voice Inspection, or ASDM management connections are vulnerable. (CVE-2010-1581, CVE-2010-2814, CVE-2010-2815)

  • A DoS vulnerability in the SIP inspection engine. (CVE-2010-2816)

  • An unspecified DoS vulnerability in the IKE implementation. (CVE-2010-2817)

A remote, unauthenticated attacker could cause the device to reload by exploiting any of these issues.
