CVE-2024-23454: Apache Hadoop: Temporary File Local Information Disclosure

[Shilun Fan <slfan1989 () apache org>]

Severity: low

Affected versions:

- Apache Hadoop before 3.4.0

Description:

Apache Hadoop’s RunJar.run() does not set permissions for temporary directory by default. If sensitive data will be 
present in this file, all the other local users may be able to view the content.
This is because, on unix-like systems, the system temporary directory is
shared between all local users. As such, files written in this directory,
without setting the correct posix permissions explicitly, may be viewable
by all other local users.

This issue is being tracked as HADOOP-19031
