+Subject: [PATCH] Use SHA256 not MD5 as default digest.
+
+Commit f8547f62c212837dbf44fb7e2755e5774a59a57b upstream.
+
+Upstream-Status: Backport
+Backport from OpenSSL 2.0 to OpenSSL 1.0.2
+Commit f8547f62c212837dbf44fb7e2755e5774a59a57b
+
+CVE: CVE-2004-2761
+
+ The MD5 Message-Digest Algorithm is not collision resistant,
+ which makes it easier for context-dependent attackers to
+ conduct spoofing attacks, as demonstrated by attacks on the
+ use of MD5 in the signature algorithm of an X.509 certificate.
