Denial of Service vulnerability in Multiple Vendor Shared Memory Operating systems with shared memory implementations based on BSD 4.4 code allow a user to conduct a denial of service and bypass memory limits (e.g., as specified with rlimits) using mmap or shmget to allocate memory and cause page faults.
Link Following vulnerability in Freebsd 2.2 FreeBSD allows local users to conduct a denial of service by creating a hard link from a device special file to a file on an NFS file system.
