an unprivileged, authenticated user with access to a GPFS node to read
arbitrary files available on this node.
CVSS Base Score: 6.2
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/
147373 for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N)

Affected Products and Versions

All fix pack levels of IBM DB2 V10.5 and V11.1.1 editions running on AIX and
Linux are affected, and only for those customers who have DB2(R) pureScale(TM)
