5a5e6db0ab Fix EPS DOS on _open -- CVE-2021-28677
* The readline used in EPS has to deal with any combination of \r and
  \n as line endings. It used an accidentally quadratic method of
  accumulating lines while looking for a line ending.
* A malicious EPS file could use this to perform a DOS of Pillow in
  the open phase, before an image was accepted for opening.
* This dates to the PIL Fork

480f6819b5 Fix Memory DOS in Icns, Ico and Blp Image Plugins
Some container plugins that could contain images of other formats,
such as the ICNS format, did not properly check the reported size of
the contained image. These images could cause arbitrariliy large
memory allocations.

This is fixed for all locations where individual *ImageFile classes
are created without going through the usual Image.open method.
