  - An ext/date/lib/parse_date.c out-of-bounds read affecting the php_parse_date function.

  - The openssl extension PEM sealing code did not check the return value of the OpenSSL sealing
  function.

  - lack of bounds checks in the date extension's timelib_meridian parsing code.

  - A stack-based buffer overflow in the zend_ini_do_op() function in the 'Zend/zend_ini_parser.c'
  script.

  - The GIF decoding function gdImageCreateFromGifCtx in gd_gif_in.c in the GD Graphics Library
  (aka libgd) does not zero colorMap arrays before use.

  - Heap buffer overread (READ: 1) finish_nested_data from unserialize
