8.0.1
-----
Security
========
Update FreeType used in binary wheels to `2.10.4`_ to fix :cve:`CVE-2020-15999`:
- A heap buffer overflow has been found in the handling of embedded PNG bitmaps,
introduced in FreeType version 2.6.
If you use option ``FT_CONFIG_OPTION_USE_PNG`` you should upgrade immediately.
We strongly recommend updating to Pillow 8.0.1 if you are using Pillow 8.0.0, which improved support for bitmap fonts.
In Pillow 7.2.0 and earlier bitmap fonts were disabled with ``FT_LOAD_NO_BITMAP``, but it is not
clear if this prevents the exploit and we recommend updating to Pillow 8.0.1.
Pillow 8.0.0 and earlier are potentially vulnerable releases, including the last release
to support Python 2.7, namely Pillow 6.2.2.
