In libzypp before 20170803 it was possible to retrieve unsigned packages without a warning to the user which could lead to man in the middle or malicious servers to inject malicious RPM packages into a users system.
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.
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.
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 path traversal in handling the "path" component of .repo files processed by libzypp before 17.38.13 in the 17.x series, or before 16.22.19 could be used by attackers to fill directories on the system outside of the zypp cache with content.
