CVE-2019-11500 (opens in a new tab)How to fix?
Upgrade Debian:11 dovecot to version 1:2.3.7.2-1 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream dovecot package and not the dovecot package as distributed by Debian.
See How to fix? for Debian:11 relevant fixed versions and status.
In Dovecot before 2.2.36.4 and 2.3.x before 2.3.7.2 (and Pigeonhole before 0.5.7.2), protocol processing can fail for quoted strings. This occurs because '\0' characters are mishandled, and can lead to out-of-bounds writes and remote code execution.
