openSUSE Security Update: Security update for rsync ______________________________________________________________________________ Announcement ID: openSUSE-SU-2018:0101-1 Rating: moderate References: #1028842 #1062063 #1066644 #1071459 #1071460 #915410 #999847 Cross-References: CVE-2014-9512 CVE-2017-16548 CVE-2017-17433 CVE-2017-17434 Affected Products: openSUSE Leap 42.3 openSUSE Leap 42.2 ______________________________________________________________________________ An update that solves four vulnerabilities and has three fixes is now available. Description: This 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) Patch Instructions: To install this openSUSE Security Update use YaST online_update.
