Synopsis: USN-2415-1 can now be patched using Ksplice
CVEs: CVE-2014-4608 CVE-2014-7975

Systems running Ubuntu 10.04 Lucid can now use Ksplice to patch
against the latest Ubuntu Security Notice, USN-2415-1.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on Ubuntu 10.04 Lucid
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

* Improved fix to CVE-2014-4608: Memory corruption in kernel lzo decompressor.

The original upstream fix for CVE-2014-4608 did not cover all cases and
was still exploitable.


* CVE-2014-7975: Denial-of-service in do_umount.

A missing capability check in do_umount allows unprivileged local users to
remount the root file system read-only, causing a denial-of-service (loss
of writability).
