CVE-2016-0701
Last modified
CVE-2016-0701 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 83.64% chance of exploitation in the next 30 days.
