CVEID: CVE-2016-0797
DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a NULL pointer dereference in the BN_hex2bn/BN_dec2bn() function. An attacker could exploit this vulnerability using specially crafted data to cause a denial of service.
CVSS Base Score: 3.7
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/111142 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L)
CVEID: CVE-2016-0799
DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by a memory error in the BIO_*printf() functions. An attacker could exploit this vulnerability using specially crafted data to trigger an out-of-bounds read.
