CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N)
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.
CVSS Base Score: 5.9
CVSS Temporal Score: Seehttps://exchange.xforce.ibmcloud.com/vulnerabilities/134397for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N)
CVEID:CVE-2017-3732
DESCRIPTION:OpenSSL could allow a remote attacker to obtain sensitive information, caused by a carry propagating bug in the x86_64 Montgomery squaring procedure. An attacker could exploit this vulnerability to obtain information about the private key.
CVSS Base Score: 5.3
CVSS Temporal Score: Seehttps://exchange.xforce.ibmcloud.com/vulnerabilities/121313for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)
