USN-1563-1: Linux kernel (Oneiric backport) vulnerability
10 September 2012
The system could be made to crash under certain conditions.
Releases
Packages
- linux-lts-backport-oneiric - Linux kernel backport from Oneiric
Details
A flaw was found in the Linux kernel's Reliable Datagram Sockets (RDS)
protocol implementation. A local, unprivileged user could use this flaw to
cause a denial of service. (CVE-2012-2372)
Mathias Krause discovered an information leak in the Linux kernel's TUN/TAP
device driver. A local user could exploit this flaw to examine part of the
kernel's stack memory. (CVE-2012-6547)
A flaw was found in Linux kernel's validation of CIPSO (Common IP Security
Option) options set from userspace. A local user that can set a socket's
CIPSO options could exploit this flaw to cause a denial of service (crash
the system). (CVE-2013-0310)
Update instructions
The problem can be corrected by updating your system to the following package versions:
Ubuntu 10.04
-
linux-image-3.0.0-25-generic
-
3.0.0-25.41~lucid1
-
linux-image-3.0.0-25-server
-
3.0.0-25.41~lucid1
-
linux-image-3.0.0-25-generic-pae
-
3.0.0-25.41~lucid1
-
linux-image-3.0.0-25-virtual
-
3.0.0-25.41~lucid1
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.
