CVE-2022-39243

NuProcess is an external process execution implementation for Java. In all
the versions of NuProcess where it forks processes by using the JVM’s
Java_java_lang_UNIXProcess_forkAndExec method (1.2.0+), attackers can use
NUL characters in their strings to perform command line injection. Java’s
ProcessBuilder isn’t vulnerable because of a check in ProcessBuilder.start.
NuProcess is missing that check. This vulnerability can only be exploited
to inject command line arguments on Linux. Version 2.0.5 contains a patch.
As a workaround, users of the library can sanitize command strings to
remove NUL characters prior to passing them to NuProcess for execution.
