Ubuntu Security Notice USN-2843-3
December 17, 2015

linux-raspi2 vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 15.10

Summary:

Several security issues were fixed in the kernel.

Software Description:
- linux-raspi2: Linux kernel for Raspberry Pi 2

Details:

郭氞刚 discovered that the ppp implementation in the Linux kernel did
not ensure that certain slot numbers are valid. A local attacker with the
privilege to call ioctl() on /dev/ppp could cause a denial of service
(system crash). (CVE-2015-7799)

Dmitry Vyukov discovered that the Linux kernel's keyring handler attempted
to garbage collect incompletely instantiated keys. A local unprivileged
attacker could use this to cause a denial of service (system crash).
(CVE-2015-7872)

It was discovered that the virtual video osd test driver in the Linux
kernel did not properly initialize data structures. A local attacker could
use this to obtain sensitive information from the kernel. (CVE-2015-7884)

It was discovered that the driver for Digi Neo and ClassicBoard devices did
not properly initialize data structures. A local attacker could use this to
obtain sensitive information from the kernel. (CVE-2015-7885)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 15.10:
linux-image-4.2.0-1016-raspi2 4.2.0-1016.23

After a standard system update you need to reboot your computer to make
all the necessary changes.

ATTENTION: Due to an unavoidable ABI change the kernel updates have
been given a new version number, which requires you to recompile and
reinstall all third party kernel modules you might have installed. If
you use linux-restricted-modules, you have to update that package as
well to get modules which work with the new kernel version. Unless you
manually uninstalled the standard kernel metapackages (e.g. linux-generic,
linux-server, linux-powerpc), a standard system upgrade will automatically
perform this as well.
