CVE-2020-28896 Open this link in a new tabHow to fix?
Upgrade RHEL:8 mutt to version 5:2.0.7-1.el8 or higher.
This issue was patched in RHSA-2021:4181.
NVD Description
Note: Versions mentioned in the description apply only to the upstream mutt package and not the mutt package as distributed by RHEL.
See How to fix? for RHEL:8 relevant fixed versions and status.
Mutt before 2.0.2 and NeoMutt before 2020-11-20 did not ensure that $ssl_force_tls was processed if an IMAP server's initial server response was invalid. The connection was not properly closed, and the code could continue attempting to authenticate. This could result in authentication credentials being exposed on an unencrypted connection, or to a machine-in-the-middle.
