https://exchange.xforce.ibmcloud.com/vulnerabilities/103778 for the current
score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)
CVEID: CVE-2015-1789
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an
out-of-bounds read in X509_cmp_time. An attacker could exploit this
vulnerability using a specially crafted certificate or CRL to trigger a
segmentation fault.
CVSS Base Score: 5
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/103779 for the current
