Description Andrej Nemec 2016-12-19 08:17:14 UTC 
This is an information disclosure vulnerability in the short-circuit reads feature of HDFS. A local user on an HDFS DataNode may be able to craft a block token that grants unauthorized read access to random files by guessing certain fields in the token.

Created hadoop tracking bugs for this issue:

Affects: fedora-all [bug 1405925]
Comment 2 Christopher Tubbs 2017-03-06 19:04:40 UTC 
This will be fixed by Hadoop 2.7.3 in F26, but I'm not sure much can really be done about F25 and earlier with Hadoop 2.4.1. Upstream does not have a fix which can be easily-backported and the current package maintainer doesn't have time to research a custom fix.
