Vulnerability Details
CVEID: CVE-2017-3737
DESCRIPTION: OpenSSL could allow a remote attacker to bypass security
restrictions, caused by a flaw in the \"error state\" mechanism when directly
calling SSL_read() or SSL_write() for an SSL object after receiving a fatal
error. An attacker could exploit this vulnerability to bypass the decryption or
encryption process and perform unauthorized actions.which is no longer an
option since CVE-2016-0701.
CVSS Base Score: 5.3
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
136077 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N)
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/
