A junit4 security update has been released for Debian GNU/Linux 8 Extended LTS to address an issue where the test rule TemporaryFolder contains a local information disclosure vulnerability.

ELA-303-1 junit4 security update

Package junit4
Version 4.11-3+deb8u1
Related CVEs CVE-2020-15250

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 8 jessie, these problems have been fixed in version 4.11-3+deb8u1.

We recommend that you upgrade your junit4 packages.
