ALERT LINUX KERNEL COMPROMISE http://www.theregister.co.uk/2009/08/14/critical_linux_bug/ :-[

Quote from: uelsk8s on August 16, 2009, 06:05:54 pm
A patched kernel for 6.0 is here:
ftp://ftp.osuosl.org/pub/vectorlinux/veclinux-6.0/kernels/kernel-2.6.27.29-i686-1vl60.tlz
ftp://ftp.osuosl.org/pub/vectorlinux/veclinux-6.0/kernels/kernel-modules-2.6.27.29-i686-1vl60.tlz
ftp://ftp.osuosl.org/pub/vectorlinux/veclinux-6.0/kernels/kernel-src-2.6.27.29-i686-1vl60.tlz

and 5.9 here:
ftp://ftp.osuosl.org/pub/vectorlinux/veclinux-5.9/kernels/kernel-2.6.27.29-i686-1vl59.tlz
ftp://ftp.osuosl.org/pub/vectorlinux/veclinux-5.9/kernels/kernel-modules-2.6.27.29-i686-1vl59.tlz
ftp://ftp.osuosl.org/pub/vectorlinux/veclinux-5.9/kernels/kernel-src-2.6.27.29-i686-1vl59.tlz

Thanks to rbistolfi for building the 5.9 kernel
download the kernels and install like any other package.
You will need the kernel and kernel-module packages, the kernel-src package is optional and only needed to build kernel and drivers
After you install run vliloconf or manually add the new kernel to your bootloader.
After rebooting with the new kernel and verifying that it works on your system, you may remove the older kernel if you want.

1. Is there some way to do this kernel update using gslapt?

2.  How do I tell what patches if any have already been added to my kernel?

Thx

Since the report only indicates affected kernels up to 2.6.30.4 this shouldn't be an issue with the VL-SOHO 6.0beta 2 which has kernel 2.6.31.6. Am I correct?

Kernel packages cant be installed with Gslapt. The problem is that gslapt updates by default, removing the older package. If the new kernel doesnt work for you, you are stuck with a non bootable system. However, installing from command line is very easy, here are the exact commands:

Code: [Select]
installpkg ftp://ftp.osuosl.org/pub/vectorlinux/veclinux-6.0/kernels/kernel-2.6.27.29-i686-1vl60.tlz
installpkg ftp://ftp.osuosl.org/pub/vectorlinux/veclinux-6.0/kernels/kernel-modules-2.6.27.29-i686-1vl60.tlz
installpkg ftp://ftp.osuosl.org/pub/vectorlinux/veclinux-6.0/kernels/kernel-src-2.6.27.29-i686-1vl60.tlz
vliloconf
Everything as root, as usual.
Thanks uelsk8s for the packages.

Where did you see that versions up to 2.6.30.4 are affected?

This is report is months old and I thought the kernel 2.6.27.29 packages fixed the vulnerability. Did I miss something? I installed those packages on all my computers as soon as they were available.

In light of GrannyGeek's comment not too sure I needed to update kernel in VL6.0, but I did and it worked great.

Thanks uelsk8s

Uelsk8s posted a link and I followed another link in that article that told more about the vulnerabilty (http://archives.neohapsis.com/archives/fulldisclosure/2009-08/0174.html). The other link implies that the fix may leave something to be desired (http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=e694958388c50148389b0e9b9e9e8945cf0f1b98). But perhaps the author comments have led to a "proper" fix in later kernels.

HTH,
Mike

I don't understand a word of those links, so I'll have to trust our VL devs to issue kernel updates if they're necessary.

Is there a place I can put a shell script which will do the update next time I restart the computer, then remove itself so it would only do it once?

Oh, this message shocked me a bit because I ran Linux 2.6.27.12 for a relatively long time... :o

But now it's fixed, installed Linux 2.6.31.8 and it's working fine, thank you uelsk8s for compiling them! :)

Now my question about this:
After installing them, I can select the new kernel as operating system when Lilo boots. How do I set Lilo that it boots the new kernel by default?
EDIT: I'll install VL 7.0, didn't know there's a brand new version! Thank you for making it! :) BTW, will there be a 7.0 Light edition?

Drawo, the KDE version was released after this news broke. It uses the patched kernel mentioned above, no need to upgrade.

Oh yes, and very stable, my old AMD Athlon xp1800+ with Nvidia and Riva TNT drivers is like new.
I like that computer, i now that he can not work forever... But so long as it works why buy a new one, money grows not in my garden, that sould be good !
Greetings, and have a nice Sunday,
