496245aa43 Fix BLP DOS -- CVE-2021-28678
* BlpImagePlugin did not properly check that reads after jumping to
  file offsets returned data. This could lead to a DOS where the
  decoder could be run a large number of times on empty data
* This dates to Pillow 5.1.0

22e9bee4ef Fix DOS in PSDImagePlugin -- CVE-2021-28675
* PSDImagePlugin did not sanity check the number of input layers and
  vs the size of the data block, this could lead to a DOS on
  Image.open prior to Image.load.
* This issue dates to the PIL fork

ba65f0b08e Fix Memory DOS in ImageFont
* A corrupt or specially crafted TTF font could have font metrics that
  lead to unreasonably large sizes when rendering text in
  font. ImageFont.py did not check the image size before allocating
  memory for it.
* Found with oss-fuzz
* This dates from the PIL fork

bb6c11fb88 Fix FLI DOS -- CVE-2021-28676
* FliDecode did not properly check that the block advance was
  non-zero, potentally leading to an infinite loop on load.
* This dates to the PIL Fork
* Found with oss-fuzz

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

3bf5eddb89 Fix OOB Read in Jpeg2KDecode CVE-2021-25287,CVE-2021-25288
* For J2k images with multiple bands, it's legal in to have different
  widths for each band, e.g. 1 byte for L, 4 bytes for A
* This dates to Pillow 2.4.0

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.
