Security scan software (twistlock) flags netty-all-4.1.52.Final.jar as a medium

{color:#000000}Netty is an open-source, asynchronous event-driven network
application framework for rapid development of maintainable high performance
protocol servers & clients. In Netty before version 4.1.59.Final there is a
vulnerability on Unix-like systems involving an insecure temp file. When
netty\'s multipart decoders are used local information disclosure can occur via
the local system temporary directory if temporary storing uploads on the disk
is enabled. On unix-like systems, the temporary directory is shared between all
user. As such, writing to this directory using APIs that do not explicitly set
the file/directory permissions can lead to information disclosure. Of note,
this does not impact modern MacOS Operating Systems. The method
'File.createTempFile' on unix-like systems creates a random file, but, by
default will create this file with the permissions '-rw-r--r--'. Thus, if
sensitive information is written to this file, other local users can read this
information. This is the case in netty\'s 'AbstractDiskHttpData' is vulnerable.
This has been fixed in version 4.1.59.Final. As a workaround, one may specify
your own 'java.io.tmpdir' when you start the JVM or use
'DefaultHttpDataFactory.setBaseDir(...)' to set the directory to something that
is only readable by the current user.{color}

The scan report shows that the issue is addressed in version 4.1.59. Is there a
plan to upgrade it?
