Ubuntu 12.04 LTS Gets a New Kernel to Patch Some Vulnerabilities

The users of this distribution from Canonical have been advised to update the OS

Several security vulnerabilities that were discovered in the Linux kernel, affecting the Ubuntu 12.04 LTS (Precise Pangolin) operating system, have been announced by Canonical.

According to Canonical, an information leak has been discovered in the Linux kernel, that occurred when inotify was used to monitor the /dev/ptmx device.

A local user could have exploited this flaw to discover a keystroke timing and potentially discover sensitive information like password length.

The security flaws can be fixed if you upgrade your system(s) to linux-image-3.2.0-48-generic (3.2.0-48.74).

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.
