Arch Linux Security Advisory ASA-202101-1
=========================================
Severity: High
Date : 2021-01-04
CVE-ID : CVE-2020-14387
Package : rsync
Type : man-in-the-middle
Remote : Yes
Link : https://security.archlinux.org/AVG-1374
Summary
=======
The package rsync before version 3.2.3-2 is vulnerable to man-in-the-
middle.
Resolution
==========
Upgrade to 3.2.3-2.
# pacman -Syu "rsync>=3.2.3-2"
The problem has been fixed upstream but no release is available yet.
Workaround
==========
None.
Description
===========
A flaw was found in rsync version 3.2.0pre1 to 3.2.4. rsync-ssl does
not verify the hostname in the server certificate in openssl mode, so a
remote, unauthenticated man-in-the-middle attacker with a valid
certificate for another hostname could intercept connections.
Impact
======
A remote, unauthenticated attacker in position of man-in-the-middle
with a valid certificate for another hostname can intercept
connections.
