Vulnerability Details

Relevant CVE Information:

CVEID: CVE-2018-0737 DESCRIPTION: OpenSSL could allow a local attacker to obtain sensitive information, caused by a cache-timing side channel attack in the RSA Key generation algorithm. An attacker with access to mount cache timing attacks during the RSA key generation process could exploit this vulnerability to recover the private key and obtain sensitive information.
CVSS Base Score: 3.3
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/141679&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N)

CVEID: CVE-2018-0732 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by the sending of a very large prime value to the client by a malicious server during key agreement in a TLS handshake. By spending an unreasonably long period of time generating a key for this prime, a remote attacker could exploit this vulnerability to cause the client to hang.
CVSS Base Score: 3.7
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/144658&gt; for the current score
