Description

Viktor Dukhovni reports:

Commit f469fc6 (2010-10-02) inadvertently caused the

previous hop realm to not be added to the transit path of issued

tickets. This may, in some cases, enable bypass of capath policy in

Heimdal versions 1.5 through 7.2. Note, this may break sites that rely

on the bug. With the bug some incomplete [capaths] worked, that should

not have. These may now break authentication in some cross-realm

configurations. (CVE-2017-6594)

With Rapid7 live dashboards, I have a clear view of all the assets on my network, which ones can be exploited, and what I need to do in order to reduce the risk in my environment in real-time. No other tool gives us that kind of value and insight.
