    Multiple vulnerabilities were discovered in ModSecurity:
    Juan Galiana Lara of ISecAuditors discovered a NULL pointer
    dereference when processing multipart requests without a part header
    name (CVE-2009-1902).
    Steve Grubb of Red Hat reported that the
    'PDF XSS protection' feature does not properly handle HTTP requests to
    a PDF file that do not use the GET method (CVE-2009-1903).
  
Impact :

    A remote attacker might send requests containing specially crafted
    multipart data or send certain requests to access a PDF file, possibly
    resulting in a Denial of Service (crash) of the Apache HTTP daemon.
    NOTE: The PDF XSS protection is not enabled by default.
  
Workaround :

    There is no known workaround at this time."
