[Ksplice][Fedora-17-updates] New updates available via Ksplice (FEDORA-2012-20614)

[Jamie Iles]

Synopsis: FEDORA-2012-20614 can now be patched using Ksplice

Systems running Fedora 17 can now use Ksplice to patch against the
latest Fedora kernel update, FEDORA-2012-20614.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on Fedora 17 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

* Use-after-free in TPCI-200 IndustryPack device removal.

A use-after-free in on device removal of a TPCI-200 device could result
in a kernel crash or data corruption.


* NULL pointer dereference in tracing ring buffer.

Missing error checks in the tracing ring buffer management could result
in a NULL pointer dereference and kernel crash.


* NULL pointer dereference in IPv6 path MTU updating.

Incorrect error checks when updating the path MTU could result in using
an invalid pointer and a subsequent NULL pointer dereference.


* NULL pointer dereference in IRDA SIR network device.

An invalid check in the IRDA SIR network device driver could result in
calling a NULL pointer and crashing the kernel.


* NULL pointer dereference in IPv4 ICMP peer management.

Missing NULL pointer checks could result in a NULL pointer dereference
when managing IPv4 peers in the ICMP protocol family.


* Memory corruption in IPv4 packet defragmentation.

A race condition when checking packet defragmentation could cause packet
corruption.


* Information leaks in INET transport monitoring bytecode.

Invalid validation of monitoring bytecode could allow a malicous user to
leak a number of bytes of kernel heap memory or to crash the kernel by
reading off the end of mapped memory.


* NULL pointer dereference in bonding slave management.

Missing locking in bonding slave management could result in a NULL
pointer dereference and kernel crash.


* Denial-of-service in SCTP message sending.

The SCTP protocol implementation did not correctly release memory when
passed an invalid source buffer.  This could allow an unprivileged user
to cause a denial-of-service.
