Bad (EC)DHE parameters cause a client crash (CVE-2017-3730)
===========================================================

Severity: Moderate

If a malicious server supplies bad parameters for a DHE or ECDHE key exchange
then this can result in the client attempting to dereference a NULL pointer
leading to a client crash. This could be exploited in a Denial of Service
attack.

OpenSSL 1.1.0 users should upgrade to 1.1.0d

This issue does not affect OpenSSL version 1.0.2.

Note that this issue was fixed prior to it being recognised as a security
concern. This means the git commit with the fix does not contain the CVE
identifier. The relevant fix commit can be identified by commit hash efbe126e3.

This issue was reported to OpenSSL on 14th January 2017 by Guido Vranken. The
fix was developed by Matt Caswell of the OpenSSL development team.

Comment 3 Andreas Stieger 2017-01-26 15:52:12 UTC
This issue only affects OpenSSL 1.1 series. Currently no SUSE or openSUSE version includes openssl 1.1.
