"In junit4 the test rule TemporaryFolder contains a local information
disclosure vulnerability. On Unix like systems, the system's temporary
directory is shared between all users on that system. Because of this,
when files and directories are written into this directory they are,
by default, readable by other users on that same system. This
vulnerability does not allow other users to overwrite the contents of
these directories or files. This is purely an information disclosure
vulnerability. This vulnerability impacts you if the JUnit tests write
sensitive information, like API keys or passwords, into the temporary
folder, and the JUnit tests execute in an environment where the OS has
other untrusted users.

For Debian 9 stretch, this problem has been fixed in version
4.12-4+deb9u1.

We recommend that you upgrade your junit4 packages.

For the detailed security status of junit4 please refer to its
security tracker page at:

block directly from the DLA security advisory. Tenable has attempted
