An update that solves three vulnerabilities and has two security fixes can now be installed.

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)

Patch Instructions:

To install this SUSE update use the SUSE recommended installation methods like YaST online_update or "zypper patch".
