OpenConnect 7.08 release

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



A bunch of fixes, including Juniper compatibility with Junos Pulse 8.2
servers, and some other new form support in Juniper. We really ought to
support handling this with a 'proper' web browser, at least for the GUI
clients. The hard-coded hacks to parse known HTML forms are getting
nastier with each special case we add.

I've added a certificate torture test suite and fixed a number of the
bugs it showed with various esoteric (and not so esoteric) file
formats. Distributors, please ensure you run 'make check' in your
package build, and chase up any failures caused by the libraries you're
building against.

It supports the new DTLS 'real negotiation' support with ocserv,
instead of deciding the cipher suites in advance. And does run-time
probing for the data MTU.

Some Windows fixes, including support for point-to-point routing.

For those building against OpenSSL, this adds support for the final
OpenSSL 1.1 release. And fixes a security issue ? OpenSSL-built clients
failed to *check* that the DTLS session was actually being resumed, and
hypothetically an attacker could have captured the DTLS session by just
performing a full handshake. So the client would be exchanging IP
packets with the attacker instead of the real VPN network.

I have managed to reproduce that attack using OpenSSL-built OpenConnect
against ocserv, where it uses standard DTLS protocols. Since Cisco's
pre-1.0 version of DTLS isn't fully supported by OpenSSL for full
handshakes (it's only ever used for resumes), I wasn't trivially able
to reproduce when talking to a Cisco ASA ? but I believe it should be
possible. If you build OpenConnect against OpenSSL then you should
upgrade immediately. GnuTLS builds are not affected as they would never
succeed in performing a full negotiation in this situation anyway.
