"From Red Hat Security Advisory 2016:2588 :
An update for openssh is now available for Red Hat Enterprise Linux 7.
Red Hat Product Security has rated this update as having a security
impact of Moderate. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.
OpenSSH is an SSH protocol implementation supported by a number of
Linux, UNIX, and similar operating systems. It includes the core files
necessary for both the OpenSSH client and server.
Security Fix(es) :
* It was discovered that the OpenSSH sshd daemon fetched PAM
environment settings before running the login program. In
configurations with UseLogin= yes and the pam_env PAM module
configured to read user environment settings, a local user could use
this flaw to execute arbitrary code as root. (CVE-2015-8325)
