[Jamie Iles]

Synopsis: RHSA-2012:1445 can now be patched using Ksplice
CVEs: CVE-2012-2100

Systems running RHCK on Oracle Linux 5, Red Hat Enterprise Linux 5,
CentOS 5, Scientific Linux 5, and CentOSPlus 5 can now use Ksplice to
patch against the latest Red Hat Security Advisory, RHSA-2012:1445.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on OL5, RHEL 5, CentOS
5, Scientific Linux 5, and CentOSPlus 5 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-2012-2100: Divide-by-zero mounting an ext4 filesystem.

The sanity check added in the original CVE-2009-4307 fix relied on undefined
compiler behaviour, which meant that it worked only on specific architectures
and didn't work on x86 for example.

This fix replaces the check with a standards compliant check which works on
all architectures.
