RHEL 6 : openssl (RHSA-2010:0888)

critical Nessus Plugin ID 50642

Language:

Synopsis

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

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2010:0888 advisory.

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

A race condition flaw has been found in the OpenSSL TLS server extension parsing code, which could affect some multithreaded OpenSSL applications.
Under certain specific conditions, it may be possible for a remote attacker to trigger this race condition and cause such an application to crash, or possibly execute arbitrary code with the permissions of the application.
(CVE-2010-3864)

Note that this issue does not affect the Apache HTTP Server. Refer to Red Hat Bugzilla bug 649304 for more technical details on how to determine if your application is affected.

Red Hat would like to thank Rob Hulswit for reporting this issue.

All OpenSSL users should upgrade to these updated packages, which contain a backported patch to resolve this issue. For the update to take effect, all services linked to the OpenSSL library 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-2010:0888.
