Description
A security issue has been found in Jenkins before version 2.319. FilePath#untar does not check permission to create symbolic links when unarchiving a symbolic link. This allows agent processes to read and write arbitrary files on the Jenkins controller file system, and obtain some information about Jenkins controller file systems.
