Pardus Linux Security Advisory 2008-64            security@...dus.org.tr
------------------------------------------------------------------------
      Date: 2008-11-07
  Severity: 2
      Type: Remote
------------------------------------------------------------------------

Summary
=======

The invalid message address parsing bug is pretty  important  since  it 
allows a remote user to  send  broken  mail  headers  and  prevent  the 
recipient from accessing the mailbox afterwards,  because  the  process 
will always just crash trying to parse the header. 

Description
===========

This is assuming that the IMAP client uses FETCH ENVELOPE command,  not 
all do. 

Affected packages:

  Pardus 2008:
    dovecot, all before 1.1.6-18-3

Resolution
==========

There are update(s) for dovecot. You can update them via Package Manager
or with a single command from console: 

    pisi up dovecot
