Security Bulletin: Vulnerabilities in GSKit affect IBM Data Server Client and Driver packages(CVE-2016-0201, CVE-2015-7420 and CVE-2015-7421)

Security Bulletin


Summary

Vulnerabilities have been addressed in the GSKit component of IBM Data Server Client and Driver packages

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-2015-7420
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 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
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)

For platforms not listed above, contact Technical Support for a special build. 

The global GSKit upgrade is required for the following configurations:
 

· IBM Data Server Client with driver packages V10.5, Fix Pack 5 and if global GSKit version 8.0.50.56 or earlier.
· IBM Data Server Client with driver packages V9.7, V10.1 and any V10.5 prior to Fix Pack 5.


To determine your existing global GSKit version, run the GSKit version executable eg: gsk8ver_64.
To obtain the global GSKit: 

Login into IBM Passport Advantage. Download and install "IBM DB2 Support Files for SSL Functionality" to install the global GSKit upgrade.
