EulerOS Virtualization 2.5.0 : rsync (EulerOS-SA-2018-1244)

critical Nessus Plugin ID 117553

Synopsis

The remote EulerOS Virtualization host is missing multiple security updates.

Description

According to the versions of the rsync package installed, the EulerOS Virtualization installation on the remote host is affected by the following vulnerabilities :

- The recv_files function in receiver.c in the daemon in rsync 3.1.2, and 3.1.3-development before 2017-12-03, proceeds with certain file metadata updates before checking for a filename in the daemon_filter_list data structure, which allows remote attackers to bypass intended access restrictions.(CVE-2017-17433)

- 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)

- The parse_arguments function in options.c in rsyncd in rsync before 3.1.3 does not prevent multiple
--protect-args uses, which allows remote attackers to bypass an argument-sanitization protection mechanism.(CVE-2018-5764)

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.

Solution

Update the affected rsync packages.
