  script_tag(name:"insight", value:"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 (in the recv_files function in
 receiver.c) and also did not apply the sanitize_paths protection
 mechanism to pathnames found in 'xname follows' strings (in the
 read_ndx_and_attrs function in rsync.c), which allowed remote attackers
 to bypass intended access restrictions' (bsc#1071460).
- 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 (bsc#1071459).
- 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 (heap-based buffer
 over-read and application crash) or possibly have unspecified other
 impact by sending crafted data to the daemon (bsc#1066644).
This non-security issue was fixed:
- Stop file upload after errors like a full disk (bsc#1062063)
- Ensure -X flag works even when setting owner/group (bsc#1028842)");
