FreeBSD : isakmpd payload handling denial-of-service vulnerabilities (b7cb488c-8349-11d8-a41f-0020ed76ef5a)
Critical Nessus Plugin ID 19096
SynopsisThe remote FreeBSD host is missing a security-related update.
DescriptionNumerous errors in isakmpd's input packet validation lead to denial-of-service vulnerabilities. From the Rapid7 advisory :
The ISAKMP packet processing functions in OpenBSD's isakmpd daemon contain multiple payload handling flaws that allow a remote attacker to launch a denial of service attack against the daemon.
Carefully crafted ISAKMP packets will cause the isakmpd daemon to attempt out-of-bounds reads, exhaust available memory, or loop endlessly (consuming 100% of the CPU).
SolutionUpdate the affected package.
