Either way, it sounds weird to keep a low severity issue private.  Low

guess it was the vendor's preference?

In this case, no, Ubuntu would have preferred several days embargo for
this issue. Hypothetically speaking, Monday would have been ideal, as
we prefer to not release updates on Friday, Saturday, or Sunday.

We treat local root escalation vulnerabilities with a high priority[1].

I wish you had spoken up during the previous discussion. It was my
impression that embargoes for local privilege escalations were universally
considered deprecated.

Please do inform us privately of further local root escalations in the
future, either via security () ubuntu com or filing "private security"
bugs against the corresponding package in Launchpad.

Thanks

Embargoes tend to make things worse, see your apport patch developed during
embargo or shellshock for examples. However, if you're sure, I'm willing to
do so for Ubuntu specific bugs in future.


1: Our priorities don't directly map to issue severities, but local root
escalations are treated highly:
