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 Advisory as soon as possible. Because the vulnerability does not require a Hewlett-Packard Secure OS 1.0 patch or re-packaging of the RPM affected by the advisory, the RPMs have not been produced or tested by Hewlett-Packard. --------------------------------------------------------------- PROBLEM: Security vulnerability in ncurses4. PLATFORM: Any system running HP Secure OS software for Linux Release 1.0 DAMAGE: Potential unauthorized execution of commands by a remote users SOLUTION: Apply the appropriate RPMs (see section B below) MANUAL ACTIONS: None AVAILABILITY: The RPMs are available now. --------------------------------------------------------------- A. Background The ncurses library provides a terminal-independent method of screen handling. ncurses4 is bases on ncurses but has been made ABI compatible. A vulnerablity exists that could be exploited by an unauthorized remote user to execute commands. ncurses4 is not included in the default installation of HP Secure OS Software for Linux Release 1.0. B. Fixing the problem Hewlett-Packard recommends that customers download the RPMs listed in the following Red Hat Security Advisory: 2002-02-19 (RHSA-2002-020) Updated ncurses4 compat packages are available http://www.redhat.com/support/errata/RHSA-2002-020.html To install the security advisory 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 advisory RPM. tripwire --check --interactive 2. Install the advisory RPM from the root account. rpm -F 3. Update the tripwire database tripwire --check --interactive NOTE: The rpm -q command can be used to determine if the product is installed. Hewlett-Packard recommends applying the security advisory 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.
