Systems running Fedora 17 can now use Ksplice to patch against the
latest Fedora kernel update, FEDORA-2013-6999.

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

* CVE-2013-3230: Kernel stack information leak in L2TP sockets.

Missing initialization could allow a local user to leak kernel stack
information when receiving messages.


* CVE-2013-3225: Kernel stack information leak in Bluetooth rfcomm.

Missing data clearing operations could allow a local user to leak kernel
stack memory to userspace.


* CVE-2013-3076: Kernel stack information leak in userspace crypto API.

missing initialization could allow a local user to leak kernel stack
information when receiving results.


* CVE-2013-1959: Incorrect privilege checks in /proc/<pid>/uid_map.

Incorrect privilege checks in /proc/<pid>/uid_map could allow a local
user to escalate privileges.


* Out-of-bounds memory write in perf_event_open() system call.

Due to implicit integer truncation, an unprivileged user can corrupt
kernel memory by passing an invalid value to the perf_event_open()
system call, possibly leading to denial of service or privilege
escalation.


* Buffer overflow in HFS+ filesystem.

An implicit truncation of an inode's size could lead to a buffer overflow
that is exploitable by local users with write access to an HFS+ filesystem.


* CVE-2013-3228: Kernel stack information leak in IRDA sockets.

Missing initialization could allow a local user to leak kernel stack
information when receiving messages.


* CVE-2013-3231: Kernel stack information leak in LLC sockets.

Missing initialization could allow a local user to leak kernel stack
information when receiving messages.


* CVE-2013-3223: Kernel stack information leak in amateur radio drivers.

Missing initialization could allow a local user to leak kernel stack
information when receiving messages.


* CVE-2013-3234: Kernel stack information leak in ROSE protocol.

Missing initialization could allow a local user to leak kernel stack
information when receiving from a ROSE socket.


* CVE-2013-3224: Kernel stack information leak in Bluetooth sockets.

Receiving messages from a bluetooth socket whilst the socket is
simultaneously being shut down could leak kernel stack bytes to
userspace allowing a local user to gain information about the running
kernel.


* CVE-2013-3222: Kernel stack information leak in ATM sockets.

Missing data clearing operations could allow an unprivileged user to
leak kernel stack memory to userspace.


* Information leak in tkill() and tgkill() system calls.

Due to a lack of proper initialization, the tkill() and tgkill() system
calls may leak data from the kernel stack to an unprivileged local user.


* Kernel crash in performance monitoring system.

Due to an incorrect bit mask, a user could write to a reserved CPU bit
and crash the kernel.


* CVE-2013-3233: Kernel stack information leak in NFC sockets.

Missing initialization could allow a local user to leak kernel stack
information when receiving messages.


* CVE-2013-1979: Privilege escalation with UNIX socket credentials.

Incorrect passing of credentials over a UNIX domain socket could allow
an unprivileged user to use a setuid binary to escalate privileges to
superuser level.
