Linux Kernel Vulnerability Fixes in Ubuntu 10.04 LTS

A system update is required to plug the vulnerability

A security vulnerability that was discovered in the Linux kernel affecting the Ubuntu 10.04.4 LTS (Lucid Lynx) operating system, was announced by Canonical.

This is the kernel vulnerability found in the Linux kernel packages: CVE-2012-4530. The system could have been made to leak sensitive system information.

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.

The security flaws can be fixed if you upgrade your system(s) to the linux-image-2.6.32-45 (2.6.32-45.102).

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.
