CVEs: CVE-2013-1819

Systems running Ubuntu 12.04 Precise can now use Ksplice to patch
against the latest Ubuntu Security Notice, USN-1968-1.

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-2013-1819: Denial-of-service in XFS filesystems.

Incorrect validation of block numbers could allow local users to cause a
denial-of-service (NULL pointer dereference and system crash) or
possibly have unspecified other impact by leveraging the ability to
mount an XFS filesystem containing a metadata inode with an invalid
extent map.


* System hang in zram swap free under high memory pressure.

Incorrect locking in the zram swap freeing path could result in a system
hang when the system is under high memory pressure.

SUPPORT

Ksplice support is available at ksplice-support_ww at oracle.com.
