OpenBSD ISAKMP memory leak
|openbsd-isakmp-memory-leak (15519)||Low Risk|
Internet Security Association and Key Management Protocol (ISAKMP), when running on OpenBSD, is vulnerable to a denial of service, caused by memory leaks. A remote attacker could send a specially-crafted ISAKMP packet to cause a denial of service.
Denial of Service
For OpenBSD 3.4:
Apply the 015_isakmpd2.patch, available from the OpenBSD 3.4 errata Web site. See References.
For OpenBSD 3.3:
Apply the 020_isakmpd2.patch, available from the OpenBSD 3.4 errata Web site. See References.
