Hi,
the following CVE (Common Vulnerabilities & Exposures) id was
published for cyrus-imapd-2.2.

CVE-2009-3235[0]:
| Multiple stack-based buffer overflows in the Sieve plugin in Dovecot
| 1.0 before 1.0.4 and 1.1 before 1.1.7, as derived from Cyrus libsieve,
| allow context-dependent attackers to cause a denial of service (crash)
| and possibly execute arbitrary code via a crafted SIEVE script, as
| demonstrated by forwarding an e-mail message to a large number of
| recipients, a different vulnerability than CVE-2009-2632.

If you fix the vulnerability please also make sure to include the
CVE id in your changelog entry.
