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:  Multiple vulnerabilities in wu-ftp software.

PLATFORM: HP9000 Series 700/800 servers running HP-UX release 11.00 only.

DAMAGE:   Any user can gain root privileges.

SOLUTION: Apply the patch noted below.

AVAILABILITY:  The patches are available now.

CHANGE SUMMARY: Added VVOS patch for HP-UX release 11.04.
- -------------------------------------------------------------------------
I.
   A. Background
      Starting with HP-UX release 11.00, Hewlett-Packard has made
      available the ported wu-ftp code.  There are buffer overruns in
      the wu-ftpd plus corrections to other client functionality as
      mentioned in AUSCERT AA-1999.02 Advisory, dated 19 October 1999.
      See www.auscert.org.au.

      HP-UX release 10.20 supports only our legacy ftp and is not affected.
      Release 11.00 is, however, vulnerable and needs this patch.  Our
      patch addresses the vulnerabilities that have been fixed in the
      2.6.0 release of wu-ftpd which has been made available by the
      WU-FTPD Development Group.

** REVISED 01 **
   B. Fixing the problem -
      For HP-UX release 11.00, install patch PHNE_18377;
- ->>>> for HP-UX release 11.04, install patch PHNE_20681.
