Hi,

A few days have passed since the optionsbleed disclosure. Some
interesting things have surfaced, e.g. the fact that it was apparently
discovered already in 2014, but nobody noticed it was a security bug.


But I'd like to discuss something else:
I had informed the distros mailing list one week earlier about the
upcoming disclosure with a bug description and links to the already
available patch.
My understanding is that the purpose of the distros list is that
updates can be prepared so after a disclosure the time between "vuln is
known" and "patch is available" is short.
However from all I can see this largely didn't happen.

Debian+Ubuntu took more than a day after disclosure to fix. According
to the Debian bug tracker the bug got only opened after the public
disclosure[2]. I see no sign that any work on a fix began before the
disclosure.

If I can trust Red Hat's CVE tracker [3] there still are no fixed
packages available. Also I haven't found any info about updated

https://www.suse.com/security/cve/CVE-2017-9798/

We have released openSUSE Leap and SUSE Linux Enterprise 12 SP2/SP3 updates.

Where did you look and not find this?

SUSE has rated the issue as moderate severity (bordering on important),
as exploitability seems difficult and not targetable.

So we were not targeting a "same as CRD day release" as with other more
severe issues, but have now released updates in the next days after the CRD.

In general predisclosure is useful for us, same as for the others for 
evaluation and preparation of critical security issues.

Ciao, Marcus
