ECO KIT SUMMARY:
A dupatch-based, Early Release Patch kit exists for Tru64 UNIX 5.1
that contains solutions for several CDE, NFS and NIS related potential
security vulnerabilities.
A number of potential security vulnerabilities have recently been
discovered for CDE, libc, NIS and NFS released with Tru64 UNIX 5.1
where under certain circumstances, system integrity may be compromised.
Compaq has corrected the following potential security vulnerabilities:
- CDE
o dtaction potential buffer overflow (SSRT0752U)
o ttsession potential buffer overflow (SSRT0753U)
o dtprintinfo potential buffer overflow (SSRT0757U)
CERT Vulnerability Note #860296 summarizes this
potential vulnerability:
http://www.kb.cert.org/vuls/id/860296
o dtprintinfo potential corefile write problem (SSRT0788U)
CERT Vulnerability Note #860296 summarizes this
potential vulnerability:
http://www.kb.cert.org/vuls/id/860296
o dtspcd potential buffer overflow (SSRT0782U)
Compaq has not been able to reproduce the problem identified
in the CERT advisory for any Compaq OS. However with the
information available, we are including a code change for
TRU64 UNIX that will further reduce any potential overflow
vulnerability.
CERT Advisory CA-2001-31 and CA-2002-01 summarizes this
potential vulnerability:
http://www.cert.org/advisories/CA-2001-31.html
http://www.cert.org/advisories/CA-2002-01.html
- Environment Variable LANG and LOCPATH
o libc potential environment variable corruption with
LANG and LOCPATH, may cause buffer overflow (SSRT0771U)
- NIS
o ypbind may core during nmap portscan (SSRT0781U)
The following customer-readable Compaq Service Advisory is also
available:

The Patch Kit Installation Instructions and the Patch Summary and Release
Notes documents provide patch kit installation and removal instructions
and a summary of each patch. Please read these documents prior to
installing patches on your system.
The patches in this ERP kit will also be available in the next mainstream
patch kit - Tru64 UNIX 5.1 Patch Kit 5.
INSTALLATION NOTES:
Install this kit with the dupatch utility that is included in the patch
kit. You may need to baseline your system if you have manually changed
system files on your system. The dupatch utility provides the baselining
capability.
INSTALLATION PREREQUISITES:
You must have installed Tru64 UNIX 5.1 PK4 (BL18) prior to installing
this Early Release Patch Kit.
KNOWN PROBLEMS WITH THE PATCH KIT:
None.
