FreeBSD Security Advisory FreeBSD-SA-02:22 - Local users can cause the FreeBSD system to crash due to a bug in the virtual memory management system involving a failure to check for the existence of a VM object during page invalidation. This bug could be triggered by calling msync(2) on an anonymous, asynchronous memory map (i.e. created using the mmap flags MAP_ANON and MAP_NOSYNC) which had not been accessed previously, causing the system to crash.
