Vulnerability Details
CVEID:
CVE-2015-7420
DESCRIPTION:
A vulnerability in GSKit could allow a remote attacker to obtain sensitive
information. The GSKit PRNG 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.
CVSS Base Score: 3.7
CVSS Temporal Score: See
https://exchange.xforce.ibmcloud.com/vulnerabilities/107694
for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/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
CVSS Vector: (CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N)
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
