[Errata Announcements for Oracle Linux]

Synopsis: 2.6.18-308.20.1.0.1.el5 can now be patched using Ksplice
CVEs: CVE-2012-2100

Users with Oracle Linux Premier Support can now use Ksplice to patch
against the latest Oracle kernel update, 2.6.18-308.20.1.0.1.el5.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on EL 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.
