Ubuntu Security Notice USN-1575-1
September 19, 2012
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 10.04 LTS
Several security issues were fixed in the kernel.
- linux-lts-backport-oneiric: Linux kernel backport from Oneiric
Ben Hutchings reported a flaw in the Linux kernel with some network drivers
that support TSO (TCP segment offload). A local or peer user could exploit
this flaw to to cause a denial of service. (CVE-2012-3412)
Jay Fenlason and Doug Ledford discovered a bug in the Linux kernel
implementation of RDS sockets. A local unprivileged user could potentially
use this flaw to read privileged information from the kernel.
The problem can be corrected by updating your system to the following
Ubuntu 10.04 LTS:
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.
