3. Description:
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.
4. Solution:
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to
use the Red Hat Network to apply this update are available at
http://kbase.redhat.com/faq/docs/DOC-11259
