Canonical announced that a regression has been found in the Linux kernel packages, this time affecting the OMAP4 kernel of the Ubuntu 12.04 (Precise Pangolin) operating system.
A few vulnerabilities were fixed in the Linux kernel but a regression was identified. Due to an unrelated regression, inotify/fanotify stopped working after upgrading. This update
repairs this problem the problem.
A complete description of the vulnerabilities can be found in the Ubuntu Security Notice.
The security flaws can be fixed if you upgrade your system to the linux-image-3.2.0-1425-omap4 package. Don't forget to reboot your computer after the upgrade!
ATTENTION: Due to an unavoidable ABI change, the kernel packages have a new version number, which will force you to reinstall and recompile all third-party kernel modules you might have installed. Moreover, if you use the linux-restricted-modules package, you have to update it as well to get modules that work with the new Linux kernel version.
