openSUSE Security Update : rsync (openSUSE-2018-34)
High Nessus Plugin ID 106063
SynopsisThe remote openSUSE host is missing a security update.
DescriptionThis update for rsync fixes the 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).
- CVE-2014-9512: Prevent attackers to write to arbitrary files via a symlink attack on a file in the synchronization path (bsc#915410).
These non-security issues were fixed :
- Stop file upload after errors like a full disk (boo#1062063)
- Ensure -X flag works even when setting owner/group (boo#1028842)
SolutionUpdate the affected rsync packages.
