HEWLETT-PACKARD COMPANY SECURITY BULLETIN: #023
Originally issued: 13 February '02
---------------------------------------------------------------
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 the
customer's failure to fully implement instructions in this Security
Bulletin as soon as possible.
Because the vulnerability does not require a HP Secure OS
1.0 patch or re-packaging of the RPM affected by the bulletin, the
RPMs have not been produced or tested by Hewlett-Packard Company.
---------------------------------------------------------------
PROBLEM: Buffer overflow in telnet server
PLATFORM: Any system running HP Secure OS software for Linux Release 1.0
DAMAGE: Potential unauthorized execution of commands with root privileges
SOLUTION: Apply the appropriate RPMs (see section B below)
MANUAL ACTIONS: None
AVAILABILITY: The RPMs are available now.
---------------------------------------------------------------
A. Background
A malicious local user could exploit a buffer overflow in the
telnet server to gain root access. Telnet server is not included
in the default installation of HP Secure OS Software for Linux.
B. Fixing the problem
Hewlett-Packard Company recommends that customers download the RPMs
listed in the following Red Hat Security Advisory:
2002-02-07 telnet (RHSA-2001:099-09) New telnet packages available to
fix buffer overflow vulnerabilities
http://www.redhat.com/support/errata/RHSA-2001-099.html
To install the security bulletin RPMs, use the following sequence
of commands:
1. If you use the tripwire product, we recommend that you run a
a consistency check and fix any violations before installing
the security bulletin RPM.
tripwire --check --interactive
2. Install the bulletin RPM from the root account.
rpm -F <bulletin RPM name>
3. Update the tripwire database
tripwire --check --interactive
NOTE:
The rpm -q <package name> command can be used to determine if the
package is installed. Hewlett-Packard Company recommends applying the
Security Bulletin fixes to installed packages only. The -F option
to the RPM installer will only apply the fix if the package is
currently installed on the system. Dependent RPMs can be found by
using the "Find Latest RPMs" search facility at
http://www.redhat.com/apps/download. To find the latest dependent
RPM enter the RPM's name in the "By Keyword" box.
