CVE-2016-0701

Исходное описание

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.

Затронутое ПО

• OpenSSL = 1.0.2= 1.0.2d= 1.0.2c= 1.0.2e= 1.0.2a= 1.0.2b точное совпадение
