    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.
