DESCRIPTION:
A security issue has been reported in nginx, which can be exploited
by malicious people to conduct spoofing attacks.

The security issue is caused due to the application not properly
verifying the server SSL certificate while using proxy functionality.
This can be exploited to e.g. spoof the server via a MitM
(Man-in-the-Middle) attack and e.g. disclose potentially sensitive
information.

The security issue is reported in version 1.2.6. Other versions may
also be affected.

SOLUTION:
No official solution is currently available.
