USN-1578-1: Linux kernel (OMAP4) vulnerabilities

Releases

• Ubuntu 11.10

Packages

• linux-ti-omap4 - Linux kernel for OMAP4

Details

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.
(CVE-2012-3430)

Update instructions

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

Ubuntu 11.10

• linux-image-3.0.0-1216-omap4 - 3.0.0-1216.28

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.
