  * SECURITY UPDATE: denial of service and possible code execution from
    integer overflow in libgd. Although the system libgd was fixed in USN-557-1,
    php5 would not gracefully handle the error return code, resulting in a
    denial of service.
    - debian/patches/219_SECURITY_CVE-2007-3996.patch: check return codes when
      calling libgd in ext/gd/gd.c.
    - CVE-2007-3996
  * SECURITY UPDATE: php_admin_value and php_admin_flag restrictions bypass via
    ini_set. (LP: #228095)
    - debian/patches/220_SECURITY_CVE-2007-5900.patch: add new
      zend_alter_ini_entry_ex() function that extends zend_alter_ini_entry() by
      making sure the entry can be modified in Zend/zend_ini.{c,h},
      Zend/zend_vm_def.h, and Zend/zend_vm_execute.h. Use the new function for
      bacporting reasons in sapi/cgi/cgi_main.c and sapi/cli/php_cli.c.
    - CVE-2007-5900
  * SECURITY UPDATE: denial of service and possible arbitrary code execution
    via crafted font file. (LP: #286851)

      font->h, and font->w don't cause overflows in ext/gd/gd.c. Also, add
      test script ext/gd/tests/imageloadfont_invalid.phpt.
    - CVE-2008-3658
  * SECURITY UPDATE: denial of service and possible arbitrary code execution
    via the delimiter argument to the explode function. (LP: #286851)
    - debian/patches/222_SECURITY_CVE-2008-3659.patch: make sure needle_length
      is sane in ext/standard/tests/strings/explode_bug.phpt. Also, add test
      script ext/standard/tests/strings/explode_bug.phpt.
    - CVE-2008-3659
  * SECURITY UPDATE: denial of service via a request with multiple dots
    preceding the extension. (ex: foo..php) (LP: #286851)

    settings.
