OpenSSL 1.1.0 < 1.1.0e Vulnerability

high Nessus Plugin ID 97328

Language:

Synopsis

The remote service is affected by a vulnerability.

Description

The version of OpenSSL installed on the remote host is prior to 1.1.0e. It is, therefore, affected by a vulnerability as referenced in the 1.1.0e advisory.

- 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. (CVE-2017-3733)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to OpenSSL version 1.1.0e or later.
