Description:
Some vulnerabilities have been identified in OpenBSD, which can be exploited by malicious, local users to cause a DoS (Denial of Service).
The vulnerabilities are caused due to errors in the semctl(), semop(), and sysctl() functions when handling certain arguments, which may cause a crash.
