Linux Kernel CD-ROM Driver Exploit Closed in Ubuntu 12.10

Users have been urged to update the system as quickly as possible

A security vulnerability that was discovered in the Linux kernel affecting the Ubuntu 12.10 (Quantal Quetzal) operating system, was announced by Canonical.

Several security issues have been fixed in the kernel. According to Canonical, an information leak has been found in the Linux kernel's CD-ROM driver. A local user could have exploited this leak to obtain sensitive information from kernel memory, if the CD-ROM drive is malfunctioning.

The security flaws can be fixed if you upgrade your system(s) to the linux-image-3.5.0-39 (3.5.0-39.60).

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.
