CVEID: CVE-2017-3738
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by an overflow bug in the AVX2 Montgomery multiplication procedure used in exponentiation with 1024-bit moduli. An attacker could exploit this vulnerability to obtain information about the private key. Note: In order to exploit this vulnerability, the server would have to share the DH1024 private key among multiple clients, which is no longer an option since CVE-2016-0701.
CVSS Base Score: 3.1
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/136078 for the current score
