you?"</blockquote>

<h2><a href="#issue-1">Issue #1 - CVEs Are Not Useful</a></h2>
|
|
<blockquote>"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..."</blockquote>
|
|
<p>- Lennart Poettering, systemd lead developer</p>
|
|
<p><b>My thoughts:</b> CVEs are supposed to be for security, and a log of when they
|
|
were found and their severity, so yes, it <em>is</em> the correct way to
|
|
announce it. It seems as if over 95 security-concious people think the same.</p>

<h2><a href="#issue-3">Issue #3 - Blaming the User</a></h2>
|
|
<blockquote><p>"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.</p>
|
|
<p>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.</p>
|
|
<p>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></blockquote>
|
|
<p>- Lennart Poettering, systemd lead developer</p>
|
|
<p><b>My thoughts:</b> systemd was the thing that allowed root access just because a
|
|
username started with a number, then Poettering blamed the user.</p>
