Various systemd vulnerabilities

Postby Head_on_a_Stick » 2019-01-12 11:09

The bloated code base of systemd hides many potential vulnerabilities, some new ones have just been uncovered:

Hopefully they'll be fixed soon.

Well thanks for the heads-up, my first reaction was check the backport ver, but it's 239 and the problems have been fixed in ver 240 FWICT?

Even if we get these fixed, I'm thinking yeah maybe tip of the iceberg. Hard to find the bugs, hard to implement the fixes. Some of these go way back.

I didn;t spend any time at all trying to understand what the bugs are or how serious or anything... why bother? nothing to do about it anyway.

Before we all get carried away, please note that the vulnerabilities are local in nature unless systemd-journal-remote is enabled, which is unlikely.

Thank $(deity)! I dread the day systemd causes the end of the human race as seemingly predicted by some correspondents. We all thought it would be climate change, pollution, or global nuclear war. :mrgreen:

That's great. Thanks for keeping people aware of the work being done.

Thank the gods and goddesses, I mean it's not like most of these machines are connected to the internet and every single exploit to shell as a user has been patched on these multiuser machines! Wait, you mean there are other bugs that allow a remote attacker to get a local shell?

Oh wait. Any vulnerability in some random piece of software that lets a remote attacker get a limited shell on a system is *drum roll* all of a sudden a local presence. And now able to gain root with these exploits. Way to understand what's going on here.

Here's hoping the bugfixes don't insert new bugs, but I won't hold my breath.

Just for the record: I don't understand the vulnerabilities at all, nor have I claimed to. I was just letting people know about them.

Btw you have some spittle on your chin, perhaps wipe it off? :mrgreen:

Well then you are contributing to the problem. If you "don't understand" whats going on don't say "everything's fine, nothing to worry about". Especially when there actually ARE issues that should worry anyone who looks at the actual vulnerabilities for more than half a second.

And where did I say that?

I linked to the actual bug reports in the OP, the post which attracted your ire was an attempt to stop the tin-foil hat wearing conspiracy theorist nutcases from hi-jacking the thread.

Also, what problem, exactly? Have you run out of tin-foil? :mrgreen:

Are you intentionally being obtuse?
Let's see, you said:

[/code]

Emphasis added. You completely ignore that it is a local SHELL that can be elevated.

Yeah, I'm almost out of tin foil because I know that there are still tons of vulnerabilities in systems that can lead to a local shell escape. Silly me for thinking logically that an attacker on my systems would not stop at a single exploit :roll:

Did I question your assertion?

My statement was taken from the Debian bug reports, perhaps go whine at them instead?

Please refrain from further off-topic posting else the thread will be locked.
