TITLE: SSRT1-85U - xntpd potential buffer overflow
SOURCE: Compaq Computer Corporation,
Software Security Response Team
====================================================
Date: 02-MAY-2001
SEVERITY: HIGH
PROBLEM STATEMENT SUMMARY:
Compaq continues to take a serious approach to the quality
and security of all its software products and makes every
effort to address issues and provide solutions in a timely
manner. In line with this commitment, Compaq is responding
to recent concerns of a potential buffer overflow with xntpd.
The Network Time Protocol daemon for Compaq Tru64 UNIX
contains a potential buffer overflow (even though it would be
difficult to exploit) that may allow unauthorized access to bin
privileges.
IMPACT:
Compaq's Tru64 UNIX V4.0d, V4.0f, V4.0g, V5.0, V5.0a, V5.1
SOLUTION:
Compaq Tru64 UNIX engineering has provided a fix for this
potential problem.
NOTE: The solutions will be included in future releases of
Tru64 UNIX aggregate patch kits. Until that has happened
the kits identified should be reinstalled accordingly after an
upgrade to any affected version listed.
The patches identified are available from the Compaq FTP site
http://ftp1.support.compaq.com/public/dunix/ then choose the
version directory needed and search for the patch by name.
Please review the applicable readme and install files prior
to installation.
