[Ksplice][EL6-Updates] Early update for remote code execution over UDP (CVE-2016-10229)

[Gregory Herrero]

Synopsis: Early update for remote code execution over UDP (CVE-2016-10229)

We felt 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 vulnerable to this issue.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running OL 6, RHEL 6,
CentOS 6, and Scientific Linux 6 install these 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


DESCRIPTION

* CVE-2016-10229: Remote code execution when receiving UDP packet with short buffers.

Incorrect handling of checksums for short receive buffers could result in
applications failing to receive data from a UDP socket. A remote attacker
could use this flaw to execute arbitrary code.
