Synopsis: 3.2.0-69.103 can now be patched using Ksplice
CVEs: CVE-2014-3601 CVE-2014-5471 CVE-2014-5472

Systems running Ubuntu 12.04 Precise can now use Ksplice to patch
against the latest Ubuntu kernel update, 3.2.0-69.103.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on Ubuntu 12.04 Precise
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-2014-5471, CVE-2014-5472: Privilege escalation in ISO filesystem implementation.

The parse_rock_ridge_inode_internal() function in the ISO filesystem driver
does not correctly check relocated directories when processing Rock Ridge
child link tags. An attacker with physical access to the system could use a
specially crafted ISO image to cause a denial of service or, potentially,
escalate their privileges.


* CVE-2014-3601: Denial-of-service in KVM page mapping.

The kvm map pages function miscalculates the number of pages in the case
of a mapping failure, which allows guest OS users to (1) cause a denial of
service (host OS memory corruption) or possibly have unspecified other
impact by triggering a large gfn value or (2) cause a denial of service
(host OS memory consumption) by triggering a small gfn value that leads to
permanently pinned pages.
