(ClamAV: Multiple vulnerabilities)

    Nikolaos Rangos discovered a vulnerability in ClamAV which exists
    because the recipient address extracted from email messages is not
    properly sanitized before being used in a call to 'popen()' when
    executing sendmail (CVE-2007-4560). Also, NULL pointer dereference
    errors exist within the 'cli_scanrtf()' function in libclamav/rtf.c and
    Stefanos Stamatis discovered a NULL pointer dereference vulnerability
    within the 'cli_html_normalise()' function in libclamav/htmlnorm.c
    (CVE-2007-4510).
  
Impact :

    The unsanitized recipient address can be exploited to execute arbitrary
    code with the privileges of the clamav-milter process by sending an
    email with a specially crafted recipient address to the affected
    system. Also, the NULL pointer dereference errors can be exploited to
    crash ClamAV. Successful exploitation of the latter vulnerability
    requires that clamav-milter is started with the 'black hole' mode
    activated, which is not enabled by default.
  
Workaround :

    There is no known workaround at this time."
