The pfs_getextattr function in FreeBSD 7.x prior to 7.3-RELEASE and 8.x prior to 8.0-RC1 unlocks a mutex that was not previously locked, which allows local users to cause a denial of service (kernel panic), overwrite arbitrary memory locations, and possibly execute arbitrary code via vectors related to opening a file on a file system that uses pseudofs.
