Package : dovecot
Vulnerability : programming error
Problem-Type : remote
Debian-specific: no
CVE ID : CVE-2007-6598

It was discovered that Dovecot, a POP3 and IMAP server, only when used
with LDAP authentication and a base that contains variables, could allow
a user to log in to the account of another user with the same password.

For the unstable distribution (sid), this problem has been fixed in
version 1.0.10-1.

For the stable distribution (etch), this problem has been fixed in
version 1.0.rc15-2etch3.

The old stable distribution (sarge) is not affected.

We recommend that you upgrade your dovecot packages.

Upgrade instructions
