    It was discovered that cyrus-imapd, a highly scalable mail system designed
    for use in enterprise environments, is not properly parsing mail headers
    when a client makes use of the IMAP threading feature.  As a result, a NULL
    pointer is dereferenced which crashes the daemon.  An attacker can trigger
    this by sending a mail containing crafted reference headers and access the
    mail with a client that uses the server threading feature of IMAP.
    
    
    For the oldstable distribution (lenny), this problem has been fixed in
    version 2.2.13-14+lenny6.
    
    For the stable distribution (squeeze), this problem has been fixed in
    version 2.2.13-19+squeeze3.
    
    For the testing (wheezy) and unstable (sid) distributions, this problem has been
    fixed in cyrus-imapd-2.4 version 2.4.11-1.
    
    
    We recommend that you upgrade your cyrus-imapd-2.2 packages.
