Security Bulletin

Summary

IBM InfoSphere BigInsights 4.2 is affected by Open Source vulnerabilities in 
Hadoop (CVE-2016-3086, CVE-2016-5001) and Solr (CVE-2017-3163)

Vulnerability Details

CVEID: CVE-2016-3086

DESCRIPTION: Apache Hadoop could allow a remote attacker to obtain sensitive 
information, caused by a flaw in the YARN NodeManager. A remote attacker could
exploit this vulnerability to obtain the password for credential store 
provider.

CVSS Base Score: 5.3

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/131544 for the current 
score

CVSS Environmental Score*: Undefined

CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N)

CVEID: CVE-2016-5001

DESCRIPTION: Apache Hadoop could allow a local authenticated attacker to 
obtain sensitive information, caused by a flaw in the short-circuit reads 
feature. By using a specially-crafted block token, a local attacker could 
exploit this vulnerability to obtain sensitive information.

CVSS Base Score: 5.5

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/131248 for the current 
score

CVSS Environmental Score*: Undefined

CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N)

CVEID: CVE-2017-3163

DESCRIPTION:

When using the Index Replication feature, Apache Solr nodes can pull index 
files from a master/leader node using an HTTP API which accepts a file name. 
However, Solr before 5.5.4 and 6.x before 6.4.1 did not validate the file 
name, hence it was possible to craft a special request involving path 
traversal, leaving any file readable to the Solr server process exposed. Solr
servers protected and restricted by firewall rules and/or authentication would
not be at risk since only trusted clients and users would gain direct HTTP 
access.

CVSS Base Score: 5.3

CVSS Temporal Score: See 
https://exchange.xforce.ibmcloud.com/vulnerabilities/131320 for the current 
score

CVSS Environmental Score*: Undefined
