Bug 792576 (CVE-2020-14387) – <net-misc/rsync-3.2.3-r5: improper TLS validation in rsync-ssl script (CVE-2020-14387)

• Product: Gentoo Security
• Status: RESOLVED FIXED

[Description Sam James 2021-05-28 03:00:43 UTC]

Description:
"A flaw was found in rsync in versions since 3.2.0pre1. Rsync improperly validates certificate with host mismatch vulnerability. A remote, unauthenticated attacker could exploit the flaw by performing a man-in-the-middle attack using a valid certificate for another hostname which could compromise confidentiality and integrity of data transmitted using rsync-ssl. The highest threat from this vulnerability is to data confidentiality and integrity. This flaw affects rsync versions before 3.2.4."
