EulerOS Virtualization 3.0.2.2 : rsync (EulerOS-SA-2020-1497)

critical Nessus Plugin ID 135659

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 receive_xattr function in xattrs.c in rsync 3.1.2 and 3.1.3-development does not check for a trailing '\0' character in an xattr name, which allows 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.(CVE-2017-16548)

- 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)

- 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)

- rsync 3.1.3-development before 2017-10-24 mishandles archaic checksums, which makes it easier for remote attackers to bypass intended access restrictions. NOTE:
the rsync development branch has significant use beyond the rsync developers, e.g., the code has been copied for use in various GitHub projects.(CVE-2017-15994)

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.
