Mandrake Linux Security Advisory : ipsec-tools (MDKSA-2006:020)
Critical Nessus Plugin ID 20809
SynopsisThe remote Mandrake Linux host is missing one or more security updates.
DescriptionThe Internet Key Exchange version 1 (IKEv1) implementation (isakmp_agg.c) in ipsec-tools racoon before 0.6.3, when running in aggressive mode, allows remote attackers to cause a denial of service (null dereference and crash) via crafted IKE packets, as demonstrated by the PROTOS ISAKMP Test Suite for IKEv1.
The updated packages have been patched to correct this problem.
SolutionUpdate the affected packages.
