We recommend that all users of Ksplice Uptrack on Debian 7.0 Wheezy
install these updates.

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,

take any action.

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y


DESCRIPTION

* CVE-2016-4470: Kernel panic when adding a negative key to a keyring.

A logic error in the kernel keyring subsystem can cause a write to an
uninitialized pointer which can trigger kernel memory corruption and a
kernel panic.


* CVE-2016-5829: Memory corruption in unknown USB HID devices.

The USB HID driver does not validate USB data when an unknown HID device
is encountered which can allow a malicious USB device to trigger kernel
memory corruption and gain execution.


* CVE-2016-5696: Session hijacking in TCP connections.

A logic error in the core TCP subsystem can allow attackers to easily
guess secret information and inject arbitrary packets into a TCP stream.


* CVE-2016-6828: Use after free during TCP transmission.

A logic error when a memory allocation fails during TCP transmission can
cause the kernel TCP stack to use freed memory causing a kernel panic.


* CVE-2016-6480: Denial-of-service in Adaptec AACRAID driver.

A race condition in fetching parameters from userspace could result in
accessing beyond the bounds of a buffer.  A local user with privileges
to access the device could use this flaw to crash the system.


* CVE-2016-7118: Denial-of-service in Aufs filesystem fcntl().

A missing NULL pointer check could allow a local, unprivileged user to
crash the system by calling an appropriate fcntl() on a file on an Aufs
filesystem.
