Summary:

Software Description:
- cpio: a tool to manage archives of files

Details:

Ingo Brückl discovered that cpio contained a path traversal vulnerability.
If a user or automated system were tricked into extracting a specially
crafted cpio archive, an attacker could possibly use this issue to write
arbitrary files outside the target directory on the host, even if using the
option --no-absolute-filenames.
