library, informed us that the former correction to several off-by-one
errors are not sufficient. For completeness please find the original
bug description below :

  Several problems were discovered in libcurl, a multi-protocol file
  transfer library. The Common Vulnerabilities and Exposures project
  identifies the following problems :

    - CVE-2005-3185
      A buffer overflow has been discovered in libcurl that
      could allow the execution of arbitrary code.

    - CVE-2005-4077
      Stefan Esser discovered several off-by-one errors that
      allows local users to trigger a buffer overflow and
      cause a denial of service or bypass PHP security
      restrictions via certain URLs."
