    It was discovered that Exim, the default mail transport agent in
    Debian, uses DKIM data obtain from DNS directly in a format string,
    potentially allowing malicious mail senders to execute arbitrary code.
    (CVE-2011-1764)
    
    The oldstable distribution (lenny) is not affected by this problem
    because it does not contain DKIM support.
    
    For the stable distribution (squeeze), this problem has been fixed in
    version 4.72-6+squeeze1.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 4.75-3.
    
    We recommend that you upgrade your exim4 packages.
