Description: A vulnerability has been reported in HP-UX, which can be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to a boundary error within "pfs_mountd.rpc" daemon when handling certain UDP packets. This can be exploited to cause a buffer overflow by sending two specially crafted UDP packets to the daemon.
Successful exploitation allows execution of arbitrary code.
The vulnerability is reported in versions HP-UX B.11.00 (obsolete), B.11.11 and B.11.23.
NOTE: PFS is reportedly obsolete since 2004-03-01 and no longer supported on any HP-UX release, but is supplied with HP-UX B.11.00, B.11.11, and B.11.23.
Solution: Use the enhanced CDFS and mount/umount commands by applying the patches. The vendor also recommends discontinuing the use of PFS.
HP-UX B.11.00:
Install PHKL_28060, PHKL_26450, PHCO_26449 or subsequent, discontinue use of PFS.
HP-UX B.11.11:
Install PHKL_28025, PHKL_26269, PHCO_25841 or subsequent, discontinue use of PFS.
HP-UX B.11.23:
Discontinue use of PFS.
