[Ksplice][Debian 6.0 Updates] Local privilege escalation update available for CVE-2014-4699.

[Quentin Casasnovas]

Synopsis: Early update for local privilege escalation using ptrace:
CVE-2014-4699.

We felt that it's important 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-2014-4699: Privilege escalation in ptrace() RIP modification.

Missing validation of the RIP value could allow an unprivileged user to
cause the CPU to fetch instructions from a non-canonical address.  On
some CPUs this could result in a denial-of-service or potentially allow
escalation of 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.

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y
