[Secure-testing-team] Bug#836706: certificate spoofing via crafted SASL messages

[Antoine Beaupré]

Source: inspircd
Version: 2.0.5-1+deb7u2
Severity: critical
Tags: security

inspircd published 2.0.23 that fixes an issue with SASL
authentication. The details are here:

http://www.inspircd.org/2016/09/03/v2023-released.html

All versions are affected.

Upstream hasn't requested a CVE yet. I will contact oss-security to
make sure that happens.

It seems to also affect Charybdis, which fixed the issue in the
upcoming 3.5.3 release:

https://github.com/charybdis-ircd/charybdis/commit/818a3fda944b26d4814132cee14cfda4ea4aa824

I will take care of the 3.5.3 upload or backporting those patches to
3.5.2 and 3.4 (if relevant) as soon as I can.
