Vulnerability Details
CVE-ID: CVE-2014-3570
Description: An unspecified error in OpenSSL related to the production of incorrect results on some platforms by Bignum squaring (BN_sqr) has an unknown attack vector and impact.
CVSS Base Score: 2.6
CVSS Temporal Score: See <http://exchange.xforce.ibmcloud.com/#/vulnerabilities/99710> for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:H/Au:N/C:N/I:P/A:N)
CVE-ID: CVE-2014-3572
Description: OpenSSL could provide weaker than expected security. The client accepts a handshake using an ephemeral ECDH ciphersuite with the server key exchange message omitted. An attacker could exploit this vulnerability to launch further attacks on the system.
CVSS Base Score: 1.2
CVSS Temporal Score: See <http://exchange.xforce.ibmcloud.com/#/vulnerabilities/99705> for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:L/AC:H/Au:N/C:N/I:P/A:N)
CVE-ID: CVE-2014-8275
Description: OpenSSL could allow a local attacker to bypass security restrictions, caused by the modification of the fingerprint without breaking the signature. An attacker could exploit this vulnerability using non-DER or invalid encodings outside the signed portion of a certificate bypass security restrictions and perform unauthorized actions.
CVSS Base Score: 1.2
CVSS Temporal Score: See <http://exchange.xforce.ibmcloud.com/#/vulnerabilities/99709> for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:L/AC:H/Au:N/C:N/I:P/A:N)
CVE-ID: CVE-2015-0204
Description: A vulnerability in the OpenSSL ssl3_get_key_exchange function could allow a remote attacker to downgrade the security of certain TLS connections. An OpenSSL client accepts the use of an RSA temporary key in a non-export RSA key exchange ciphersuite. This could allow a remote attacker using man-in-the-middle techniques to facilitate brute-force decryption of TLS/SSL traffic between vulnerable clients and servers. This vulnerability is also known as the FREAK attack.
CVSS Base Score: 4.3
CVSS Temporal Score: See <http://exchange.xforce.ibmcloud.com/#/vulnerabilities/99707> for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)
