<p>Anyone who cares about security may want to switch from systemd as soon as possible; its lead

developer doesn't care about your security at all.</p>

<h3>Issue #0 - Against CVE Assignment</h3>
|
|
||||||
<br>
|
|
||||||
<p>Poettering:<br>
|
|
||||||
"You don't assign CVEs to every single random bugfix we do, do you?"</p>
|
|
||||||
<br>
|
|
||||||
<p>My thoughts:<br>
|
|
||||||
Yes, if they're security-related.</p>

<h3>Issue #1 - CVEs Are Not Useful</h3>
|
|
||||||
<br>
|
|
||||||
<p>Poettering:<br>
|
|
||||||
"Humpf, I am not convinced this is the right way to announce this. We never did that, and half the
|
|
||||||
CVEs aren't useful anyway, hence I am not sure we should start with that now, because it is either
|
|
||||||
inherently incomplete or blesses the nonsensical part of the CVE circus which we really shouldn't
|
|
||||||
bless..."</p>
|
|
||||||
<br>
|
|
||||||
<p>My thoughts:<br>
|
|
||||||
CVEs are supposed to be for security, and a log of when they were found and their severity, so yes,
|
|
||||||
it *is* the correct way to announce it. It seems as if over 95 security-concious people think the
|
|
||||||
same.</p>

<h3>Issue #2 - Security is a Circus</h3>
|
|
||||||
<br>
|
|
||||||
<p>Poettering:<br>
|
|
||||||
"I am not sure I buy enough into the security circus to do that though for any minor issue..."</p>

<h3>Issue #3 - Blaming the User</h3>
|
|
||||||
<br>
|
|
||||||
<p>Poettering:<br>
|
|
||||||
"Yes, as you found out "0day" is not a valid username. I wonder which tool permitted you to create
|
|
||||||
it in the first place. Note that not permitting numeric first characters is done on purpose: to
|
|
||||||
avoid ambiguities between numeric UID and textual user names.<br>
|
|
||||||
<br>
|
|
||||||
systemd will validate all configuration data you drop at it, making it hard to generate invalid
|
|
||||||
configuration. Hence, yes, it's a feature that we don't permit invalid user names, and I'd consider
|
|
||||||
it a limitation of xinetd that it doesn't refuse an invalid username.<br>
|
|
||||||
<br>
|
|
||||||
So, yeah, I don't think there's anything to fix in systemd here. I understand this is annoying, but
|
|
||||||
still: the username is clearly not valid."</p>
|
|
||||||
<br>
|
|
||||||
<p>My thoughts:<br>
|
|
||||||
systemd was the thing that allowed root access just because a username started with a number, then
|
|
||||||
Poettering blamed the user.</p>
