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 predicable 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
