Ipsec-Tools: >> Ipsec-Tools Security Vulnerabilities
The racoon daemon in IPsec-Tools 0.8.2 contains a remotely exploitable computational-complexity attack when parsing and storing ISAKMP fragments. The implementation permits a remote attacker to exhaust computational resources on the remote endpoint by repeatedly sending ISAKMP fragment packets in a particular order such that the worst-case computational complexity is realized in the algorithm utilized to determine if reassembly of the fragments can take place.

Multiple memory leaks in Ipsec-tools before 0.7.2 allow remote attackers to cause a denial of service (memory consumption) via vectors involving (1) signature verification during user authentication with X.509 certificates, related to the eay_check_x509sign function in src/racoon/crypto_openssl.c; and (2) the NAT-Traversal (aka NAT-T) keepalive implementation, related to src/racoon/nattraversal.c.

src/racoon/handler.c in racoon in ipsec-tools does not remove an "orphaned ph1" (phase 1) handle when it has been initiated remotely, which allows remote attackers to cause a denial of service (resource consumption).

The isakmp_info_recv function in src/racoon/isakmp_inf.c in racoon in Ipsec-tools before 0.6.7 allows remote attackers to cause a denial of service (tunnel crash) via crafted (1) DELETE (ISAKMP_NPTYPE_D) and (2) NOTIFY (ISAKMP_NPTYPE_N) messages.

The Internet Key Exchange version 1 (IKEv1) implementation (isakmp_agg.c) in racoon in ipsec-tools 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.
