SEAndroid

The U.S. National Security Agency (NSA) has begun releasing Security-Enhanced Android patches and tools, which port their Security-Enhanced Linux tools to Android devices. SEAndroid and SELinux provide mandatory access control designed to limit the amount of damage that rogue or exploited software can do. [more inside]

Chowned

While many Linux users cite the system's security against malware, the appearance of malware disguised as a screensaver reminded everyone that no system is 100% safe. Ubuntu users were quick to identify the virus, identify the perpetrators, and create a fix, but this isn't the first time this has happened, and will in all likelihood not be the last. The criticism in the community is directed squarely at the user base: "In general the lesson to be learned is if you want a secure system, don't download any software outside the official package sources without at least looking at the source code first."

Why Can't MS Do This?

An 8 year old critical security bug in the Linux kernel? No problem, we can fix that without even rebooting. You heard me, it is possible to apply a source code patch to a running kernel without reboot.

15 bits of crypto should be enough for anybody

On May 13, security advisories published by Debian and Ubuntu revealed that, for over a year, their OpenSSL libraries have had a major flaw in their CSPRNG, which is used by key generation functions in many widely-used applications, which caused the "random" numbers produced to be extremely predictable.

The Winux virus

The Winux virus is reported to affect both Windows and Linux boxes/applications. The article says it's "written in a primitive computer language called 'assembly language'." On a side note, who do they get to write these articles? Certainly they are uncomfortable with technology...

Up to 20% of the internet vulnerable

Up to 20% of the internet vulnerable to a virus. There is a new Linux worm virus. Apparently, it steals passwords, installs and hides other hacking tools on infected systems, and then uses those systems to seek other servers to attack. Sys admins are advised to run a check on their servers and upgrade their BIND version.

Well, we talked about NORAD a few posts back, I guess now it's time for everyone's *other* favorite agency: the NSA has a logo. That's funny. No, really, the topic of this posting is their release of Security-Enhanced Linux, including Mandatory Access Control and other cool B-1'ish stuff. Ted T'so has some interesting observations in this Slashdot thread on the topic as well.

Apparently, the conventional wisdom is not quite right. The SDMI's Executive Director says they have "thousands of entries" in their contest to hack the various proposed digital music security schemes. As I pointed out recently in a similar context, the "Linux community" and the population of computer literate, financially motived, non-OS-sectarian hackers are far from being one and the same...

RedHat Linux security problem uncovered.

RedHat Linux security problem uncovered. Today, apparently it was discovered that if you install the Piranha package with RedHat 6.2 (ostensibly part of the default installation, but there's controversy over this), a default password is installed that would give anyone access to the Piranha configuration package; from there, it is apparently trivial to execute any command on the box that you want.
I find it very interesting that the fact that Microsoft had a "backdoor password" in a DLL made huge news (and it turned out to be patently false), yet this has gotten almost no press. I'd like to think otherwise, but I know it's because people hate Microsoft, and thus are eager to deride it... and yet here's proof that even the mighty Linux is susceptible to the same exact problems.
Next time you reach for the keyboard to cry out "nyah nyah!" at the discovery of some problem with Windows, remember this...
