Updated OpenSSH packages available

Updated OpenSSH packages are now available for Red Hat Linux 7, 7.1, and
7.2. These packages fix a vulnerability which exists when a
server is configured with the "UseLogin" option.

When the "UseLogin" option is enabled in OpenSSH, a malicious user who
authenticates using key-based authentication methods can influence the
environment variables passed to the login process. This could
allow the user to execute arbitrary code with superuser privileges.
In Red Hat Linux the OpenSSH server has the "UseLogin" option disabled
by default. Therefore, it is not vulnerable unless the system administrator
has changed this setting.

The Common Vulnerabilities and Exposures project (cve.mitre.org) has
assigned the name CAN-2001-0872 to this issue.

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

To update all RPMs for your particular architecture, run:

rpm -Fvh [filenames]

where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.

Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
