VULNERABILITY SUMMARY

A potential security vulnerability has been identified with HP-UX
running CIFS Server (Samba). This vulnerability could potentially
allow a remote unauthenticated user to cause controllable heap
corruption, leading to execution of arbitrary commands with root
privileges, or a Denial of Service (DoS).

References: CAN-2004-1154

SUPPORTED SOFTWARE VERSIONS*: ONLY impacted versions are listed.
HP-UX B.11.00, B.11.11, B.11.22, and B.11.23.

BACKGROUND

For a PGP signed version of this security bulletin please write to:
security-alert@hp.com

To determine if an HP-UX system has an affected version,
search the output of "swlist -a revision -l fileset"
for one of the filesets listed below. For affected systems
verify that the recommended action has been taken.
