PROBLEM: Vulnerabilities exist in xlock on VirtualVault 2.0/3.0 if patch
PHSS_9905 is installed.
PLATFORM: HP9000 Series 700/800s running:
HP-UX 10.24 (VVOS) with VirtualVault A.02.00 with patch PHSS_9905.
HP-UX 10.24 (VVOS) with VirtualVault A.03.00 with Extensions
Software (this includes PHSS_9905)
DAMAGE: The xlock vulnerability could result in allowing a local user
to gain unauthorized access to the system.
SOLUTION: Apply PHSS_12961 to correct the vulnerability.
AVAILABILITY: The patch is available now.
____________________________________________________________________
I.
A. Background
The xlock program allows a user to "lock" an X terminal while
maintaining their login session. A vulnerability exists in xlock
that could allow a local user to attain unauthorized access to the
system.
B. Fixing the problem
This problem can be eliminated by applying the recommended patch.
C. Recommended solution
Hewlett-Packard recommends that the PHSS_12961 patch be applied if
PHSS_9905 has already been installed. The PHSS_9905 patch is
included in the Software Extension Media provided with VirtualVault
A.03.00.
NOTE:
These problems only apply to systems running the VirtualVault
Operating System 10.24 that is part of the VirtualVault product
A.02.00 and A.03.00.
