Package: dovecot-common
Severity: important
Tags: security

Hi,
the following CVE (Common Vulnerabilities & Exposures) ids were
published for dovecot.

CVE-2008-4577[0]:
| The ACL plugin in Dovecot before 1.1.4 treats negative access rights
| as if they are positive access rights, which allows attackers to
| bypass intended access restrictions.

CVE-2008-4578[1]:
| The ACL plugin in Dovecot before 1.1.4 allows attackers to bypass
| intended access restrictions by using the "k" right to create
| unauthorized "parent/child/child" mailboxes.

The upstream announcement can be found here[2]. I don't think this warrants
a DSA for etch and for lenny it could be fixed via unstable migration.

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

Cheers
Steffen
