CWE-200  (opens in a new tab)

How to fix?

Upgrade openssl to version 1.0.2f or higher.

Overview

Affected versions of this package are vulnerable to Information Exposure. The DH_check_pub_key function in crypto/dh/dh_check.c in OpenSSL 1.0.2 before 1.0.2f does not ensure that prime numbers are appropriate for Diffie-Hellman (DH) key exchange, which makes it easier for remote attackers to discover a private DH exponent by making multiple handshakes with a peer that chose an inappropriate number, as demonstrated by a number in an X9.42 file.
