As usual, you can click on each one to see how it affects your system, or go here and here for in-depth descriptions. The security flaws can be fixed if you upgrade your system(s) to the linux-image-2.6.24-30 (2.6.24-30.97) package(s) for Ubuntu 8.04 LTS and the linux-image-2.6.35-31 (2.6.35-31.63) package(s) for Ubuntu 10.10 (Maverick Meerkat).

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 which work with the new Linux kernel version.
