New Linux Kernel Vulnerability Affects Ubuntu 11.10 OMAP4

Ubuntu 11.10 Enlarge picture - Ubuntu 11.10
A Linux kernel security vulnerability was recently discovered in the Linux kernel packages, affecting the Ubuntu 11.10 (Oneiric Ocelot) Linux kernel for OMAP4.

Nick Bowler discovered CVE-2011-4081, a Linux kernel vulnerability where error conditions were incorrectly handled by the kernel GHASH message digest algorithm, leading to a kernel oops.

This security flaw can be fixed if you upgrade your system to the linux-image-3.0.0-1206-omap4 (3.0.0-1206.13) kernel 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 which work with the new Linux kernel version.

Oh, yeah, Windows "just works" all right. Yet Windows needs two firewalls, an anti-virus, an anti-malware, and anti-spyware/adware (none of which is needed with Linux). So yeah, it "just works" after you install a minimum of three third-party security programs.

since when does windows just work? -- All your windows based colleges / friends/ family and acquaintances have perfectly running systems? Delusional if you attempt answer yes with any hoesty
.
However, I'm not loosing sleep over this.. I'm happily staying at UB10.10 until LTS or beyond, if it's even worth the upgrade... cause 11.10 is mere guinea-pig material. Dunno how many users have to migrate before Mr shuttle' sends unity into orbit - forever - I digress.

Why are you trying to sensationalize this patch as omap4 specific? First, it doesn't just affect the omap4 kernel, it affects all kernels from Lucid 10.04 forward, on all platforms. And it isn't only limited to Ubuntu.

If it only affected the 11.10 release of Ubuntu on omap4, then there is nothing to worry about, as there are only >10K panda boards that this supports sold so far.

And yes, Ubuntu does update their kernels far more often than Microsoft, or even other Linux distributions. This kernel was released 11/23, and guess what? The next updated kernel is due out next week. With more glorious fixes for the masses using an omap4 based "system" from http://pandaboard.org.
What a joke.

Sensationalize? It's a very small announcement for a single kernel vulnerability OFFICIALLY announced by Canonical for the Ubuntu 11.10 OMAP4 kernel.

Yes, sensationalizing. If you were to actually do 30 seconds of investigating and reading of your own link, you would see that it affected 13 different Ubuntu kernels on 8 platforms listed. It is also being tracked on Redhat and Gentoo.

Plus, the included picture is a snapshot from the live desktop (i386 or amd64), NOT the omap4 system (I can tell by the icons on the screen and the missing icons).
