Ubuntu Security Notice USN-2611-1
May 20, 2015
linux vulnerability
==========================
==========================
========================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 12.04 LTS
Summary:
The system could be made to crash if it received specially crafted
network traffic.
Software Description:
- linux: Linux kernel
Details:
Vincent Tondellier discovered an integer overflow in the Linux kernel's
netfilter connection tracking accounting of loaded extensions. An attacke=
r
on the local area network (LAN) could potential exploit this flaw to caus=
e
a denial of service (system crash of targeted system).
Update instructions:
The problem can be corrected by updating your system to the following
package versions:
Ubuntu 12.04 LTS:
linux-image-3.2.0-84-generic 3.2.0-84.121
linux-image-3.2.0-84-generic-pae 3.2.0-84.121
linux-image-3.2.0-84-highbank 3.2.0-84.121
linux-image-3.2.0-84-omap 3.2.0-84.121
linux-image-3.2.0-84-powerpc-smp 3.2.0-84.121
linux-image-3.2.0-84-powerpc64-smp 3.2.0-84.121
linux-image-3.2.0-84-virtual 3.2.0-84.121
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 automaticall=
y
perform this as well.
