(Mutt: Buffer overflow)

    TAKAHASHI Tamotsu has discovered that Mutt contains a boundary error in
    the 'browse_get_namespace()' function in browse.c, which can be
    triggered when receiving an overly long namespace from an IMAP server.
  
Impact :

    A malicious IMAP server can send an overly long namespace to Mutt in
    order to crash the application, and possibly execute arbitrary code
    with the permissions of the user running Mutt.
  
Workaround :

    There is no known workaround at this time."
