Vulnerability Details

CVEID: CVE-2017-3735 DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by an error while parsing an IPAdressFamily extension in an X.509 certificate. An attacker could exploit this vulnerability to trigger an out-of-bounds read, resulting in an incorrect text display of the certificate.
CVSS Base Score: 4.3
CVSS Temporal Score: <https://exchange.xforce.ibmcloud.com/vulnerabilities/131047&gt; for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N)

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.
CVSS Base Score: 5.3
CVSS Temporal Score: <https://exchange.xforce.ibmcloud.com/vulnerabilities/136077&gt; for more information
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.
CVSS Base Score: 3.1
