SUSE SLED12 / SLES12 Security Update : rsync (SUSE-SU-2018:0118-1)
High Nessus Plugin ID 106129
SynopsisThe remote SUSE host is missing one or more security updates.
DescriptionThis 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).
The update package also includes non-security fixes. See advisory for details.
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.
