+ *) rsaz_1024_mul_avx2 overflow bug on x86_64
+
+ There is an overflow bug in the AVX2 Montgomery multiplication procedure
+ used in exponentiation with 1024-bit moduli. No EC algorithms are affected.
+ Analysis suggests that attacks against RSA and DSA as a result of this
+ defect would be very difficult to perform and are not believed likely.
+ Attacks against DH1024 are considered just feasible, because most of the
+ work necessary to deduce information about a private key may be performed
+ offline. The amount of resources required for such an attack would be
+ significant. However, for an attack on TLS to be meaningful, the server
+ would have to share the DH1024 private key among multiple clients, which is
+ no longer an option since CVE-2016-0701.
+
+ This only affects processors that support the AVX2 but not ADX extensions
+ like Intel Haswell (4th generation).
+
+ This issue was reported to OpenSSL by David Benjamin (Google). The issue
+ was originally found via the OSS-Fuzz project.
+ (CVE-2017-3738)
+ [Andy Polyakov]
