This update for rsync fixes several issues. These security issues were fixed: - CVE-2017-17434: The daemon in rsync did not check for fnamecmp filenames in the daemon_filter_list data structure and also did not apply the sanitize_paths protection mechanism to pathnames found in xname follows strings , which allowed remote attackers to bypass intended access restrictions . - CVE-2017-17433: The recv_files function in receiver.c in the daemon in rsync, proceeded with certain file metadata updates before checking for a filename in the daemon_filter_list data structure, which allowed remote attackers to bypass intended access restrictions . - CVE-2017-16548: The receive_xattr function in xattrs.c in rsync did not check for a trailing "\\0" character in an xattr name, which allowed remote attackers to cause a denial of service or possibly have unspecified other impact by sending crafted data to the daemon . This non-security issue was fixed: - Stop file upload after errors like a full disk - Ensure -X flag works even when setting owner/group
