Vulnerability Details

CVEID: CVE-2016-0201 DESCRIPTION: IBM GSKit could allow a remote attacker to obtain sensitive information, caused by a MD5 collision. An attacker could exploit this vulnerability to obtain authentication credentials.
CVSS Base Score: 5.9
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/109310 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N)

CVEID: CVE-2015-7421 DESCRIPTION: A vulnerability in GSKit could allow a remote attacker to obtain sensitive information. The internal ICC PRNG pool state is duplicated during a fork() system call operation which results in a period of time where child processes may generate identical PRNG output to the parent. This may allow possible attacks related to predictable state which an attacker could exploit.
CVSS Base Score: 3.7
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/107695> for the current score
CVSS Environmental Score*: Undefined
