Dear Release Team,
The Security Team advised that CVE-2018-0486 should be fixed by a stable
update, because it isn't exploitable in the stretch version of the
Shibboleth stack, but software outside Debian could still be affected
by the issue. Stretch currently has version 1.6.0; upstream fixed this
security issue in 1.6.3 (already uploaded to unstable). Since 1.6.2 was
a revert of the most part of the changes in 1.6.1, 1.6.3 is effectively
three code changes beyond 1.6.0: the security fix itself:

a more general fix for the same issue for Xerces 3.2 (stretch has 3.1):

Based on the above, a stable update straight to 1.6.3 does not seem
unreasonable to me, but it's your call, certainly. Backporting the
first hunk (the relevant security fix) is easy enough. On the other
hand, having version numbers reflecting the reality can be useful.
So, what version number should I post the debdiff for? Please include
the Debian part as well, I haven't prepared stable updates yet.
Also, if you can estimate: when can we expect the next stable update,
that is, how much time have I got for this process?

Thanks,
Feri.
