SynopsisThe remote EulerOS Virtualization host is missing a security update.
DescriptionAccording to the version of the rsync package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerability :
- The daemon in rsync 3.1.2, and 3.1.3-development before 2017-12-03, does not check for fnamecmp filenames in the daemon_filter_list data structure (in the recv_files function in receiver.c) and also does 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 allows remote attackers to bypass intended access restrictions.(CVE-2017-17434)
Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
SolutionUpdate the affected rsync package.
