The ktimer feature (sys/kern/kern_time.c) in FreeBSD 7.0, 7.1, and 7.2 allows local users to overwrite arbitrary kernel memory via an out-of-bounds timer value.
The product performs operations on a memory buffer, but it reads from or writes to a memory location outside the buffer's intended boundary. This may result in read or write operations on unexpected memory locations that could be linked to other variables, data structures, or internal program data.
