FreeBSD : racoon remote denial of service vulnerability (ISAKMP header length field) (ccd698df-8e20-11d8-90d1-0020ed76ef5a)

Medium Nessus Plugin ID 19124


The remote FreeBSD host is missing a security-related update.


When racoon receives an ISAKMP header, it will attempt to allocate sufficient memory for the entire ISAKMP message according to the header's length field. If an attacker crafts an ISAKMP header with a ridiculously large value in the length field, racoon may exceed operating system resource limits and be terminated, resulting in a denial of service.


Update the affected package.
