Oracle Solaris 11: CVE-2015-4000: Vulnerability in LFTP, OpenSSL, Thunderbird

Severity CVSS Published Added Modified
4 (AV:N/AC:M/Au:N/C:N/I:P/A:N) May 20, 2015 May 29, 2017 October 31, 2018

Description

The TLS protocol 1.2 and earlier, when a DHE_EXPORT ciphersuite is enabled on a server but not on a client, does not properly convey a DHE_EXPORT choice, which allows man-in-the-middle attackers to conduct cipher-downgrade attacks by rewriting a ClientHello with DHE replaced by DHE_EXPORT and then rewriting a ServerHello with DHE_EXPORT replaced by DHE, aka the "Logjam" issue.
