A flaw was found in libzypp. This path traversal vulnerability, present in the handling of the "path" component within .repo files, could allow attackers to write content to directories outside of the intended zypp cache. This unauthorized writing of data can lead to a Denial of Service (DoS) by filling up disk space on the system.
