Details

There exists a race condition between the deletion of the temporary file and the creation of the temporary directory in webkit subproject of HTML/Java API version 1.7. A similar vulnerability has recently been disclosed in other Java projects and the fix in HTML/Java API version 1.7.1 follows theirs: To avoid local privilege escalation version 1.7.1 creates the temporary directory atomically without dealing with the temporary file: https://github.com/apache/netbeans-html4j/commit/fa70e507e5555e1adb4f6518479fc408a7abd0e6
