RHEL 4 / 5 : openssl (RHSA-2009:0004)

medium Nessus Plugin ID 35316

Synopsis

The remote Red Hat host is missing a security update for openssl.

Description

The remote Redhat Enterprise Linux 4 / 5 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2009:0004 advisory.

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.

The Google security team discovered a flaw in the way OpenSSL checked the verification of certificates. An attacker in control of a malicious server, or able to effect a man in the middle attack, could present a malformed SSL/TLS signature from a certificate chain to a vulnerable client and bypass validation. (CVE-2008-5077)

All OpenSSL users should upgrade to these updated packages, which contain backported patches to resolve these issues. For the update to take effect, all running OpenSSL client applications must be restarted, or the system rebooted.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL openssl package based on the guidance in RHSA-2009:0004.
