[Ksplice][EL6-Updates] Important update available for CVE-2014-0196

[Quentin Casasnovas]

Synopsis: Early update for local privilege escalation in TTY driver:
CVE-2014-0196

We felt that it's important for us to ship this update early, before
distributions released kernels that fix the problem, because our audit
showed that we have a large number of customers affected by the CVE.

DESCRIPTION

* CVE-2014-0196: Pseudo TTY device write buffer handling race.

A race in how the pseudo ttyp (pty) device handled device writes when
two threads/processes wrote to the same pty, the buffer end could be
overwritten. An attacker could use this to cause a denial-of-service or
gain root privileges.

INSTALLING THE UPDATES

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,
these updates will be installed automatically and you do not need to
take any action.
