Ubuntu: USN-2883-1 (CVE-2016-0701): OpenSSL vulnerability

Severity CVSS Published Added Modified
3 (AV:N/AC:H/Au:N/C:P/I:N/A:N) January 27, 2016 February 01, 2016 December 19, 2017

Description

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.
