    The arrayShrink function in lib/Array.c can cause an array to
    shrink to 0 entries, which triggers an assert error. NOTE: this issue
    is due to an incorrect fix for CVE-2007-6239 (CVE-2008-1612).
    An invalid version number in a HTTP request may trigger an
    assertion in HttpMsg.c and HttpStatusLine.c (CVE-2009-0478).
  
Impact :

    The issues allows for Denial of Service attacks against the service via
    an HTTP request with an invalid version number and other specially
    crafted requests.
