This issue was patched in RHSA-2019:2822.

NVD Description

Note: Versions mentioned in the description apply only to the upstream dovecot-mysql package and not the dovecot-mysql package as distributed by RHEL. See How to fix? for RHEL:8 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.
