Title: Security Advisory regarding automountd
-------------------------------------------------------------------------
HEWLETT-PACKARD COMPANY SECURITY ADVISORY: #00104, 21 Oct. 99
-------------------------------------------------------------------------
The information in the following Security Advisory should be acted upon
as soon as possible. Hewlett-Packard Company will not be liable for any
consequences to any customer resulting from customer's failure to fully
implement instructions in this Security Advisory as soon as possible.
-------------------------------------------------------------------------
PROBLEM: automountd can run user programs as root.
PLATFORM: HP-9000 Series 700/800 HP-UX releases 10.X and 11.00.
DAMAGE: Allows users to gain root privileges
SOLUTION: Temporarily set AutoFS =3D 0 in /etc/rc.config.d/nfsconf
(see below)
AVAILABILITY: No patches for 10.X and 11.00 are available at this time.
NOTE: This advisory will be revised when patches are available.
-------------------------------------------------------------------------
I.
A. Background
This problem was originally reported in CERT Advisory CA-99-05,
regarding the vulnerability in automountd which allows an
intruder to execute arbitrary commands with the privileges of
the automountd process.
We had previously reported that Hewlett-Packard platforms were
not vulnerable; we now have new information showing that we
are indeed vulnerable.
B. Fixing the problem -
At this time there are no patches available for any releases.
As a work around, setting AutoFS =3D 0 in the file
/etc/rc.config.d/nfsconf, we believe, will disallow most
exploitations. We continue to work on this problem and this
advisory will be updated when patches become available.
