"This update for rsync fixes the following issues: Security issues
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).

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues."
