Synopsis

The remote Scientific Linux host is missing one or more security updates.

Description

An information leak flaw was found in the way the OpenSSH client roaming feature was implemented. A malicious server could potentially use this flaw to leak portions of memory (possibly including private SSH keys) of a successfully authenticated OpenSSH client.
(CVE-2016-0777)

A buffer overflow flaw was found in the way the OpenSSH client roaming feature was implemented. A malicious server could potentially use this flaw to execute arbitrary code on a successfully authenticated OpenSSH client if that client used certain non-default configuration options.

After installing this update, the OpenSSH server daemon (sshd) will be restarted automatically.
