    the string processing code may lead to denial of service
    and potentially the execution of arbitrary code.

  - CVE-2008-2663
    Drew Yao discovered that multiple integer overflows in
    the string processing code may lead to denial of service
    and potentially the execution of arbitrary code.

  - CVE-2008-2664
    Drew Yao discovered that a programming error in the
    string processing code may lead to denial of service and
    potentially the execution of arbitrary code.

  - CVE-2008-2725
