The information in this Security bulletin should be acted upon
as soon as possible.
INITIAL RELEASE: 26 July 2004
POTENTIAL SECURITY IMPACT: remote root access
SOURCE: HEWLETT-PACKARD COMPANY
HP Software Security Response Team
REFERENCES: CAN-2004-0686
VULNERABILITY SUMMARY:
A potential security vulnerability has been identified with HP-UX
running the CIFS Server. This buffer overflow could potentially
be exploited remotely to gain root access.
SUPPORTED SOFTWARE VERSIONS*: ONLY impacted versions are listed.
HP-UX B.11.00, B.11.11, B.11.22, B.11.23.
BACKGROUND:
AFFECTED VERSIONS
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.11.23
HP-UX B.11.22
HP-UX B.11.11
HP-UX B.11.00
=============
For revision A.01.11.01 and previous:
CIFS-Server
action: Please see the Resolution section.
END AFFECTED VERSIONS
Note: The HP CIFS Server versions do not map directly to
original Samba versions. The what(1) output will show
the HP version string, for example: A.01.11.02. Samba
commands such as "smbd -V" or "smbstatus" will report the
underlying base Samba version, for example: 2.2.10.
Note: The HP CIFS Server versions A.01.11.02 and previous are
not affected by the vulnerability reported in CAN-2004-0600.
RESOLUTION:
Until an update is available the potential vulnerability can
be avoided by setting "mangling method = hash2" or
"mangled names = no" in smb.conf.
Note: CIFS Server installations requiring the hash mangling
method must evaluate the impact of converting to the
hash2 mangling method.
MANUAL ACTIONS: Yes - NonUpdate
Until a product update is available, modify smb.conf as described
in the Resolution section.
