[Michael Ploujnikov]

Synopsis: FEDORA-2012-12684 can now be patched using Ksplice
CVEs: CVE-2012-3520

Systems running Fedora 16 can now use Ksplice to patch against the
latest Fedora kernel update, FEDORA-2012-12684.

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

* CVE-2012-3520: privilege escalation in netlink socket credential passing.

Under certain circumstances the kernel could pass zeroed credentials to
userspace causing the application to mistakenly see credentials for the
superuser resulting in a possible privilege escalation.


* Kernel panic on removal of large amount of files.

A failure to initialize a loop counter can lead to a kernel panic
when attempting to remove a large amount of files.


* Memory corruption in FUSE handling of vectored responses.

An incorrect check of the size of the response vector could lead to an
overflow and corruption of memory after the vector.


* Invalid memory access in xHCI ring queue handling.

An incorrect dequeuing of items from the xHCI ring queue can
cause general protection faults by accessing invalid memory regions.


* NULL pointer dereference handling scsi over IB command responses.

A NULL dereference will occur if a reply to a previous request would happen
during or after an abort command.
