PluginScript attempts to chroot the plugin to the repoManagerRoot, this root is frequently / (the system root) in standard configurations or when using --root. If the chroot target is /, it is a no-op, allowing the traversed path to execute host binaries (like /bin/bash) with root privileges.

A relative path traversal in the "keyhint" option in repomd.xml parsing of libzypp before 17.38.12 can be used by attackers able to supply a malicious repository to inject or overwrite files in the target system as root.

A relative path traversal bug problem when processing repository metadata in libzypp before 17.38.10 could be used by remote attackers supplying repositories to overwrite files on the system, leading to denial of service or privilege escalation.
