[Ksplice][Fedora-16-updates] New updates available via Ksplice (FEDORA-2012-10319)

[Sasha Levin]

Synopsis: FEDORA-2012-10319 can now be patched using Ksplice

Systems running Fedora 16 can now use Ksplice to patch against the
latest Fedora kernel update, FEDORA-2012-10319.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on Fedora 16 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

* Denial of service accessing CAN devices.

A race condition when openning CAN devices may lead to interrupts
being disabled on devices, preventing them from working properly.


* Denial of service in NFS back-channel request handling.

A memory leak on the failure path of processing back-channel requests
can lead to a local denial of service.


* Denial of service in NFSd on uniprocessor hosts.

Incorrect handling of spinlock semantics on uniprocessor hosts can lead
to denial of service when closing a NFS session.


* Memory corruption in 9p virtio transport implementation.

A wrong condition used to protect against memory corruption could allow
a corruption to happen anyway.


* Denial of service processing corrupted descriptors in ATH9K driver.

A failure to properly handle corrupt descriptors can lead to kernel panic when a corrupt
descriptor is encountered.


* Denial of service in memory mappings when closing processes.

Incorrect release order of resources in the memory manager can lead to a
kernel panic when closing processes.
