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

A flaw was found in the SSH protocol. An attacker able to perform a
man-in-the-middle attack may be able to obtain a portion of plain text from
an arbitrary ciphertext block when a CBC mode cipher was used to encrypt
SSH communication. This update helps mitigate this attack: OpenSSH clients
and servers now prefer CTR mode ciphers to CBC mode, and the OpenSSH server
now reads SSH packets up to their full possible length when corruption is
detected, rather than reporting errors early, reducing the possibility of
successful plain text recovery. (CVE-2008-5161)");
  script_tag(name:"solution", value:"All OpenSSH users are advised to upgrade to these updated packages, which
contain backported patches to resolve these issues and add these
enhancements. After installing this update, the OpenSSH server daemon
(sshd) will be restarted automatically.

Please note that this update is available via
Red Hat Network.  To use Red Hat Network, launch the Red
Hat Update Agent with the following command: up2date");
