HEWLETT-PACKARD COMPANY SECURITY BULLETIN: #0156, 2 July '01
-------------------------------------------------------------------------
The information in the following Security Bulletin 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 Bulletin as soon as possible.
-------------------------------------------------------------------------
PROBLEM: The setrlimit() allows incorrect core files
PLATFORM: HP9000 Series 700/800 running HP-UX releases 10.01, 10.10,
10.20, 10.24, 11.04, and 11.00 only.
DAMAGE: Possible denial of service
SOLUTION: Install the appropriate patch for the HP-UX release:
11.11 PHKL_23423,
11.04 PHKL_23886,
11.00 PHKL_23628,
10.20 700 PHKL_22701,
10.20 800 PHKL_22702,
10.24 700 PHKL_24249,
10.24 800 PHKL_24250,
10.10 700 PHKL_23477,
10.10 800 PHKL_23478,
10.01 700 PHKL_23512,
10.01 800 PHKL_23513.
AVAILABILITY: The patches are available now.
-------------------------------------------------------------------------
A. Background
Hewlett-Packard has discovered that a process that at one time was
setuid/setgid could create corefiles or be attached to with a
debugger. If the process core file's size limit has been set to 0
in setrlimit(), when the process aborts, the core processing is
incorrect.
B. Recommended solution
After applying this patch, the kernel now remembers that the
process was at one time setuid/setgid, and disallow corefiles
and debugger attachment. If the process core file size limit
has been set to zero, it obeys.
Application of the appropriate patch selected from the list below
completely solves this problem.
For HP-UX release:
11.11 PHKL_23423,
11.04 PHKL_23886,
11.00 PHKL_23628,
10.20 700 PHKL_22701,
10.20 800 PHKL_22702,
10.24 700 PHKL_24249,
10.24 800 PHKL_24250,
10.10 700 PHKL_23477,
10.10 800 PHKL_23478,
10.01 700 PHKL_23512,
10.01 800 PHKL_23513.
Note: Many of these patches have dependencies. A reboot will
be required.
