RHEL 2.1 / 3 : openssl (RHSA-2007:0813)

medium Nessus Plugin ID 27563

Synopsis

The remote Red Hat host is missing one or more security updates.

Description

Updated OpenSSL packages that correct security issues are now available for Red Hat Enterprise Linux 2.1 and 3.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

OpenSSL is a toolkit that implements Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols as well as a full-strength general purpose cryptography library.

A flaw was found in the SSL_get_shared_ciphers() utility function. An attacker could send a list of ciphers to an application that used this function and overrun a buffer with a single byte (CVE-2007-5135). Few applications make use of this vulnerable function and generally it is used only when applications are compiled for debugging.

A number of possible side-channel attacks were discovered affecting OpenSSL. A local attacker could possibly obtain RSA private keys being used on a system. In practice these attacks would be difficult to perform outside of a lab environment. This update contains backported patches designed to mitigate these issues. (CVE-2007-3108).

Users of OpenSSL should upgrade to these updated packages, which contain backported patches to resolve these issues.

Note: After installing this update, users are advised to either restart all services that use OpenSSL or restart their system.

Solution

Update the affected openssl, openssl-devel and / or openssl-perl packages.
