Information Disclosure Vulnerability in Apache Hadoop Data Management

CVE-2016-5001

Summary

This vulnerability allows a local user on an HDFS DataNode to exploit a flaw in the short-circuit reads feature of HDFS. By crafting a specially formed block token, the user may gain unauthorized access to sensitive files on the system by manipulating certain fields within the token. This exploitation can lead to potential data leaks, allowing attackers to read files without appropriate permissions. It is crucial for users of affected Apache Hadoop versions to apply necessary updates to mitigate this risk.
