LXer: Multiple X.Org Vulnerabilities Found, One Is from 1987

Friday 12th of December 2014 06:12:06 AM
One of the most important features of the open source development community is its ability to self-correct, even if it takes a very long time. A number of issues in X servers have been corrected recently, and some of them were actually very old. The record holder is a bug introduced back in 1987.

LXer: Mozilla to Support Certificate Transparency in Firefox

Friday 12th of December 2014 05:14:55 AM
Mozilla is planning to add support for Certificate Transparency checks in Firefox in the near future, but the company says that the feature won’t be turned on by default at first. Certificate Transparency is a proposal from engineers at Google that would help resolve some of the issues with certificate authorities, fraudulent certificates and stolen certificates. The framework would provide a public log of every certificate that’s issued by compliant CAs and also would provide proof to users’ browsers when each certificate is presented. Google is planning to implement CT in Chrome, and now Mozilla officials say that the company will implement in Firefox, but the process will be a gradual one.

LXer: Ubuntu Core Linux Gets 'Snappy' for Docker Container Security

Friday 12th of December 2014 04:17:44 AM
From an application deployment perspective, applications for Snappy Ubuntu are packaged as "snaps," which provides a mechanism to help ensure package authenticity and security."Not only will users be able to validate what they downloaded is exactly what they wanted, they will also be able to validate that the current state on disk matches that at any time," Kirkland said. "The tools for this are not yet included, but are a critical piece of our security design and will become available during our beta program."

LinuxInsider: 4MLinux Is So Lightweight It's Anemic

Friday 12th of December 2014 01:38:22 AM
4MLinux is a unique mini Linux distribution that tries to be what it is not. Its limited-purpose design is too basic for even lightweight distro functions. Much of any benefit users might derive from 4MLinux mimics what already is available from USB-launched pocket Linux distros such as Puppy Linux, Porteus and Knoppix. However, much of the advanced functionality of these other distros is missing from 4MLinux. The 4MLinux name is derived from this distro's specialized uses: Multimedia, Miniserver, Maintenance and Mystery.

Reddit: Why don't more distros besides Arch support encrypted /boot on the same HD?

Thursday 11th of December 2014 11:11:46 PM

From a lot of research, it seems to me that only Arch and other distros which use mkinitcpio--mostly its derivatives or super modular distros like Gentoo--support booting from an encrypted boot partition.

As far as I can understand, you need bootloader and initramfs support to boot from an encrypted partition on the same disk. GRUB supports encrypted boot, because it will embed itself the BIOS boot partition. I tested this out with Ubuntu once and booted the Ubuntu initramfs from an encrypted LVM over LUKS boot partition from GRUB.

However, the initramfs failed to boot the Ubuntu kernel, because, AFAIK, the Ubuntu initramfs doesn't support encrypted boot partitions. In fact, AFAIK, mkinitcpio is the only initramfs which does so. If you're curious, here's a blog post on how to set up full disk encryption on Arch.

Why is encrypted boot important? It prevents meaningful change to your boot partition.

When unencrypted, I can replace your kernel with another kernel that acts the same except that it also contains a keylogger that emails logs back to myself. Or a piece of code that steals your AES keys out of RAM.

When encrypted, I can still try to modify your boot partition, but my changes, when unencrypted, will not mean anything. All that will probably happen is your kernel will fail to boot in part or whole.

It seems like it shouldn't be too much work for other distros/ initramfs to support encrypted boot. Why does there seem to be no interest in doing so?

Five Great Applications For Systems Admins

Being a systems administrator is a difficult, often thankless job. You’re one of the people responsible for keeping the entire IT infrastructure of your business up and running. What that means is that whenever something doesn’t work the way it should, all eyes immediately turn in your direction. You can hardly be blamed for looking to make your life a bit easier. I’d actually recommend that you do so, truth be told. The less time you spend slogging through all the basics of administration, the more time you can devote to improving your server. To that end, I’ve compiled a list of a few of the best sysadmin apps on the web; tools that any Linux administrator worth their salt should consider using. Read more
