Hewlett-Packard Company
HP Software Security Response Team

A potential security vulnerability has been identified with HP-UX
running perl where the potential vulnerability could be exploited
by a local user to gain unauthorized elevated privileges.


SUPPORTED SOFTWARE VERSIONS*:  ONLY impacted versions are listed.
HP-UX B.11.00, B.11.11, and B.11.23 running perl.

CAN-2005-0448  < ?
name=CAN-2005-0448>  reports a race condition in the rmtree
function in Perl prior to 5.8.4 which allows local users to create
arbitrary setuid binaries in the tree being deleted.

The changes made to address this issue in Perl 5.8.4 have been
incorporated into the HP-UX perl revisions cited below.


     Note: To determine if a system has an affected version,
           search the output of "swlist -a revision -l fileset"
           for an affected fileset.  Then determine if the
           recommended patch or update is installed.

      HP-UX B.11.00
      HP-UX B.11.11
      HP-UX B.11.23
