   An update that solves three vulnerabilities and has two
   fixes is now available.

Description:

   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)
