EulerOS Virtualization for ARM 64 3.0.2.0 : rsync (EulerOS-SA-2019-1944)

critical Nessus Plugin ID 128947

Synopsis

The remote EulerOS Virtualization for ARM 64 host is missing multiple security updates.

Description

According to the versions of the rsync package installed, the EulerOS Virtualization for ARM 64 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)

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.
