Security Fix(es):
* jenkins-2-plugins/subversion: does not restrict the name of a file when looking up a subversion key (CVE-2021-21698)
* jenkins: FilePath#mkdirs does not check permission to create parent directories (CVE-2021-21685)
* jenkins: File path filters do not canonicalize paths, allowing operations to follow symbolic links to outside allowed directories (CVE-2021-21686)
* jenkins: FilePath#untar does not check permission to create symbolic links when unarchiving a symbolic link (CVE-2021-21687)
* jenkins: FilePath#reading(FileVisitor) does not reject any operations allowing users to have unrestricted read access (CVE-2021-21688)
* coreos-installer: restrict access permissions on /boot/ignition{,/config.ign} (CVE-2021-3917)
* jenkins: FilePath#unzip and FilePath#untar were not subject to any access control (CVE-2021-21689)
* jenkins: Agent processes are able to completely bypass file path filtering by wrapping the file operation in an agent file path (CVE-2021-21690)
* jenkins: Creating symbolic links is possible without the symlink permission (CVE-2021-21691)
* jenkins: The operations FilePath#renameTo and FilePath#moveAllChildrenTo only check read permission on the source path (CVE-2021-21692)
* jenkins: When creating temporary files, permission to create files is only checked after they’ve been created. (CVE-2021-21693)
* jenkins: FilePath#toURI, FilePath#hasSymlink, FilePath#absolutize, FilePath#isDescendant, and FilePath#get*DiskSpace do not check any permissions (CVE-2021-21694)
* jenkins: FilePath#listFiles lists files outside directories with agent read access when following symbolic links. (CVE-2021-21695)
* jenkins: Agent-to-controller access control allowed writing to sensitive directory used by Pipeline: Shared Groovy Libraries Plugin (CVE-2021-21696)
* jenkins: Agent-to-controller access control allows reading/writing most content of build directories (CVE-2021-21697)
