The Sieve engine in Dovecot before 2.3.15 allows Uncontrolled Resource
Consumption, as demonstrated by a situation with a complex regular
expression for the regex extension (CVE-2020-28200).

Dovecot before 2.3.15 allows ../ Path Traversal. An attacker with access
to the local filesystem can trick OAuth2 authentication into using an HS256
validation key from an attacker-controlled location. This occurs during use
of local JWT validation with the posix fs driver (CVE-2021-29157).

The submission service in Dovecot before 2.3.15 allows STARTTLS command
injection in lib-smtp. Sensitive information can be redirected to an
attacker-controlled address (CVE-2021-33515).");
