Multiple vulnerabilities were identified in the Internet Security Association and Key Management Protocol (ISAKMP), which may be exploited by remote attackers to cause a denial of service or execute arbitrary commands. These issues are due to errors in certain ISAKMP implementations that do not properly handle IKE (Internet Key Exchange) Phase 1 packets with invalid and/or abnormal contents, which could be exploited by attackers to cause denial of service conditions or compromise vulnerable systems.

Note : The severity and impact of these vulnerabilities vary by vendor.

Affected Products

Internet Key Exchange version 1 (IKEv1)

Solution

Use packet filters and accept ISAKMP negotiations only from trusted sources.
