    Package : exim4
    Vulnerability : format string vulnerability
    Problem type : remote
    Debian-specific: no
    CVE ID : CVE-2011-1764
    Debian Bug : 624670

    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.
