Vulnerability Details

CVEID: CVE-2017-3736
Description:OpenSSL could allow a remote attacker to obtain sensitive information, caused by a carry propagation flaw in the x86_64 Montgomery squaring function bn_sqrx8x_internal(). An attacker with online access to an unpatched system could exploit this vulnerability to obtain information about the private key.

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.
