CVE-2016-0701 (GCVE-0-2016-0701)

Vulnerability from cvelistv5 – Published: 2016-02-15 00:00 – Updated: 2024-08-05 22:30
VLAI?
Summary
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.
Severity ?
