CVE-2023-7216
Cpio: extraction allows symlinks which enables remote command execution
A path traversal vulnerability was found in the CPIO utility. This issue could allow a remote unauthenticated attacker to trick a user into opening a specially crafted archive. During the extraction process, the archiver could follow symlinks outside of the intended directory, which allows files to be written in arbitrary directories through symlinks.
Fixes and workarounds
Workaround
Use the --no-absolute-filenames option to avoid this behaviour.
