DESCRIPTION:
Vasiliy Kulikov has reported two weaknesses in net6, which can be
exploited by malicious people to disclose certain information and
conduct session hijacking attacks.

1) The library may perform certain actions prior to validating the
authentication of a connecting user, which can be exploited to e.g.
disclose certain information about already connected users.

2) It's possible to cause an internal ID counter to overflow, which
can be exploited to e.g. hijack another user's session.

The weaknesses are reported in version 1.3.13. Other versions may
also be affected.

SOLUTION:
Fixed in the GIT repository.
