CVEs: CVE-2013-2141 CVE-2013-2164 CVE-2013-2206 CVE-2013-2232 CVE-2013-2234 CVE-2013-2237 CVE-2013-2851 CVE-2013-2852 CVE-2013-2888 CVE-2013-2892

Systems running Debian 6.0 Squeeze can now use Ksplice to patch
against the latest Debian Security Advisory, DSA-2766-1.

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack on Debian 6.0 Squeeze
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-2013-2164: Kernel information leak in the CDROM driver.

Incorrect allocation in the generic CDROM driver could result in leaking
heap memory to userspace.


* CVE-2013-2237: Information leak on IPSec key socket.

Incorrect initialization on policy flushing could leak kernel stack
bytes to userspace.


* CVE-2013-2852: Invalid format string usage in Broadcom B43 wireless driver.

Format string vulnerability in the b43_request_firmware function
in the Broadcom B43 wireless driver in the Linux kernel through 3.9.4
allows local users to gain privileges by leveraging root access and
including format string specifiers in an fwpostfix modprobe parameter,
leading to improper construction of an error message.


* CVE-2013-2851: Format string vulnerability is software RAID device names.

A format string vulnerability in partition registration allows local
users to execute kernel mode code by writing format string specifiers to
/sys/module/md_mod/parameters/new_array in order to create an invalid
/dev/md device name.


* CVE-2013-2232: Memory corruption in IPv6 routing cache.

Connecting an IPv6 socket to an IPv4 destination can cause IPv4 routing
information to be placed in the IPv6 routing cache causing memory corruption
and a kernel panic.


* CVE-2013-2206: NULL pointer dereference in SCTP duplicate cookie handling.

A flaw was found in the way the Linux kernel's Stream Control
Transmission Protocol (SCTP) implementation handled duplicate cookies.
If a local user queried SCTP connection information at the same time a
remote attacker has initialized a crafted SCTP connection to the system,
it could trigger a NULL pointer dereference, causing the system to
crash.


* CVE-2013-2141: Information leak in tkill() and tgkill() system calls.

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


* CVE-2013-2234: Information leak in IPsec key management.

An error in the AF_KEY implementation allows privileged users to leak contents of
the kernel stack to userspace.


* CVE-2013-2888: Memory corruption in Human Input Device processing.

The kernel does not correctly validate the 'Report ID' field in HID data allowing
a malicious USB or Bluetooth device to cause memory corruption and gain kernel
code execution.


* CVE-2013-2892: Memory corruption in Pantherlord Human Input Device processing.

Missing validation of HID report data could cause corruption of heap
memory.  A local user with physical access to the system could use this
flaw to crash the kernel resulting in DoS or potential privilege
escalation to gain root access via arbitrary code execution.


* NULL pointer dereference in HID report field setting.

Missing NULL pointer checks could result in a NULL pointer dereference
when a driver populated the results of field enquiries.
