RHEA-2012:0065 - openssh enhancement update


Synopsis

openssh enhancement update

Type/Severity

Product Enhancement Advisory

Topic

Updated openssh packages that add one enhancement are now available for Red Hat Enterprise Linux 6.

Description

OpenSSH is OpenBSD's Secure Shell (SSH) protocol implementation. These packages include the core files necessary for the OpenSSH client and server.

This update adds the following enhancement:

  • Previously, OpenSSH could use the Advanced Encryption Standard New Instructions (AES-NI) instruction set only with the AES Cipher-block chaining (CBC) cipher. This update adds support for Counter (CTR) mode encryption in OpenSSH so the AES-NI instruction set can now be used efficiently also with the AES CTR cipher. (BZ#782367)

All users of openssh are advised to upgrade to these updated packages, which add this enhancement.

Solution

Before applying this update, make sure that all previously-released errata relevant to your system have been applied.

This update is available via Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at This content is not included.https://access.redhat.com/kb/docs/DOC-11259
