Package        : dovecot
Vulnerability  : programming error
Problem type   : remote
Debian-specific: no
CVE ID         : CVE-2006-2414

A problem has been discovered in the IMAP component of Dovecot, a
secure mail server that supports mbox and maildir mailboxes, which can
lead to information disclosure via directory traversal by
authenticated users.

The old stable distribution (woody) is not affected by this problem.

For the stable distribution (sarge) this problem has been fixed in
version 0.99.14-1sarge0.

For the unstable distribution (sid) this problem has been fixed in
version 1.0beta8-1.

We recommend that you upgrade your dovecot-imapd package.
