RHBA-2013:1751 - openssl bug fix update

Synopsis

openssl bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated openssl packages that fix two bugs are now available for Red Hat Enterprise Linux 6.

Description

The openssl packages provide a toolkit that implements the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols, as well as a full-strength general-purpose cryptography library.

This update fixes the following bugs:

  • Previously, the OpenSSL code incorrectly used RDRAND instruction when running on Cyrix CPU, which does not support it. Consequently, the applications that use the OpenSSL utility terminated unexpectedly on startup. The detection of CPU features on Cyrix CPU has been fixed, and the applications using OpenSSL no longer crash in the described scenario. (BZ#1025597)

  • Prior to this update, the Transport Layer Security (TLS) client advertised support for some elliptic curves that are not supported by it. As a consequence, server could choose unsupported elliptic curve and client would not be able to communicate with the server over the TLS. With this update, OpenSSL TLS client advertises only the curves that are supported by it, and TLS communication with server (using also curves not supported by the Red Hat Enterprise Linux OpenSSL TLS client) can now be established. (BZ#1025598)

Users of openssl are advised to upgrade to these updated packages, which fix these bugs. For the update to take effect, all services linked to the OpenSSL library must be restarted, or the system rebooted.

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 https://access.redhat.com/site/articles/11258
