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)

Upgrading of global GSKit is required if either of the following applies to 
you:

   IBM Data Server Client and driver packages V10.5 Fix Pack 5 and the 
   additionally installed global GSKit version is 8.0.50.56 or less.

   IBM Data Server Client and driver packages V9.7, V10.1 level and any V10.5 
   level before Fix Pack 5.

Where to obtain the global GSKit:

Login into IBM Passport Advantage

https://www-01.ibm.com/software/passportadvantage/pao_customer.html

Download "IBM DB2 Support Files for SSL Functionality" from IBM Passport 
Advantage and perform the GSKit upgrade.

The following link gives instructions on downloading "IBM DB2 Support Files 
for SSL Functionality" from IBM Passport Advantage

http://www-01.ibm.com/support/docview.wss?uid=swg21433407

To know the existing global GSKit version in the current setup, one can run 
the GSKit version executable eg: gsk8ver_64.

Refer to the following chart below for the proper version of global GSKit that
has the fix

Release 	GSKit Version

V9.7 		V8.0.50.57

V10.1 		V8.0.50.57

V10.5 		V8.0.50.57
