    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)
