AVAILABILITY: All patches are available on <>.

CHANGE SUMMARY: Rev. 01 Final patches released
 A. Background
    A potential buffer overflow in uucp(1) and uusub has been
    identified and has now been fixed. This problem only affects
    HP-UX releases 10.20, 11.00 and 11.11.


     The following is a list by HP-UX revision of
     affected filesets or patches and fix information.
     To determine if a system has an affected version,
     search the output of "swlist -a revision -l fileset"
     for an affected fileset or patch, then determine if
     a fixed revision or applicable patch is installed.

 --> HP-UX B.11.11
     fix: install PHCO_29382 or subsequent

 --> HP-UX B.11.00
     fix: install PHCO_29381 or subsequent

 --> HP-UX B.10.20
     fix: write to for information.


      HP NonStop Servers,
      HP Tru64 UNIX/TruCluster Server,
      HP OpenVMS
      HP-UX VVOS (11.04)

    The SSRT thanks LSD Research Group ( for
    reporting this potential vulnerability to HP.

 B. Recommended solution
    The following temporary depot files MUST be removed before
    the official patch is installed. Failure to properly remove
    these could cause corruption of the system and inadvertently
    re-introduce the problem at a later time when the temporary
    patch is removed.

    The temporary files to be removed were:
          for HP-UX 11.00 PHCO_29106.depot
          for HP-UX 11.11 UNOF_29107.depot

    Now apply the appropriate patch:
               PHCO_29382 for B.11.11
               PHCO_29381 for B.11.00

    Download the patch from, copy the depot to a
    protected directory, and launch Software Distributor (SD)
    to install.

    On systems running the discontinued and obsoleted B.10.20
    continue to use the temporary depot: PHCO_29105.depot.

    and by bulletin topic. Security Patch Check completely
    automates the process of reviewing the patch matrix for
    11.XX systems. Please note that installing the patches
    listed in the Security Patch Matrix will completely
