[Jamie Iles]

Synopsis: 3.0.0-29.46 can now be patched using Ksplice
CVEs: CVE-2012-5517

Systems running Ubuntu 11.10 Oneiric can now use Ksplice to patch
against the latest Ubuntu kernel update, 3.0.0-29.46.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on Ubuntu 11.10 Oneiric
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

* Kernel panic in 802.11 frame parsing.

The generic 802.11 wireless driver does not correctly handle truncated
non-management frames leading to an out-of-bounds read and kernel
panic. This issue may be triggered by a remote attacker.


* Deadlock in NFSv4 client during recovery.

Incorrect locking could result in deadlocks in a recovery situation for NFSv4.


* Remote information leak in netfilter TCP connection tracking.

An attacker on a shared routing queue with the victim can gain information
about the victim's TCP connections by sending malformed TCP packets.


* CVE-2012-5517: NULL pointer dereference in memory hotplug.

A NULL pointer dereference can occur when a new node's hot-added
memory is propagated to other nodes zonelists. An unprivileged local
user can use this flaw to crash the system.


* NULL pointer dereference in NFS lookup code.

Fix kernel oops caused by a null pointer dereference due to
lookup_one_len() calling down to the dentry revalidation code with
a NULL pointer to struct nameidata.


* Use-after-free in L2TP Ethernet session.

The kernel L2TP driver does not correctly handle failing to initialize
a L2TPv3 Ethernet session leading to a use-after-free and kernel panic.


* Memory corruption when closing netlink sockets.

Incomplete releasing of memory in netlink could lead to intermittent
memory corruption.
