CVE-2017-3733 (opens in a new tab)Amendment
The Debian security team deemed this advisory irrelevant for Debian:9.
NVD Description
Note: Versions mentioned in the description apply only to the upstream openssl1.0 package and not the openssl1.0 package as distributed by Debian.
During a renegotiation handshake if the Encrypt-Then-Mac extension is negotiated where it was not in the original handshake (or vice-versa) then this can cause OpenSSL 1.1.0 before 1.1.0e to crash (dependent on ciphersuite). Both clients and servers are affected.
