Ubuntu 12.10 USN-1700-2 Critical: Linux Kernel OMAP4 Regression Fix

Scroller Ubuntu
Ubuntu 12.10 security patch reinstates performance following kernel issues due to USN-1700-1 release.
USN-1700-1 introduced a regression in the Linux kernel.

Summary

USN-1700-1 introduced a regression in the Linux kernel.

Software Description:

- linux-ti-omap4: Linux kernel for OMAP4

Details:

USN-1700-1 fixed vulnerabilities in the Linux kernel. Due to an unrelated

regression inotify/fanotify stopped working after upgrading. This update

fixes the problem.

We apologize for the inconvenience.

Original advisory details:

A flaw was discovered in the Linux kernel's handling of script execution

when module loading is enabled. A local attacker could exploit this flaw to

cause a leak of kernel stack contents. (CVE-2012-4530)

Florian Weimer discovered that hypervkvpd, which is distributed in the

Linux kernel, was not correctly validating source addresses of netlink

packets. An untrusted local user can cause a denial of service by causing

hypervkvpd to exit. (CVE-2012-5532)

Update Instructions

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

Ubuntu 12.10:
  linux-image-3.5.0-218-omap4     3.5.0-218.26

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.
