INSTALLING THE UPDATES
We recommend that all users of Ksplice Uptrack on RHEL 6 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
* ext4 filesystem corruption on fallocate.
Attempting to fallocate() a file over 4GB with insufficient space on an
ext4 filesystem could result in corruption of the filesystem image.
* CVE-2012-2745: Denial-of-service in kernel key management.
A potential double-free of the replacement session keyring on fork()
could result in a denial-of-service by a local, unprivileged user.
* CVE-2012-2744: Remote denial-of-service in IPv6 connection tracking.
A flaw in the IPv6 connection tracking netfilter module could allow a
remote attacker to trigger a NULL pointer dereference and
denial-of-service with specially crafted IPv6 packets.
