Description

Rapid7 has reported some vulnerabilities in OpenBSD isakmpd, which can be exploited by malicious people to cause a DoS (Denial-of-Service).

The vulnerabilities are caused due to errors within the validation and processing functions of isakmpd when handling ISAMKP messages. This can be exploited to either crash the service or cause it to enter an infinite loop by sending specially crafted ISAKMP messages to a vulnerable system.


Solution
Apply patches.
