+========
+
+Update FreeType used in binary wheels to `2.10.4`_ to fix CVE-2020-15999_:
+
+  - A heap buffer overflow has been found  in the handling of embedded PNG bitmaps,
+    introduced in FreeType version 2.6.
+
+      https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2020-15999
+
+    If you use option ``FT_CONFIG_OPTION_USE_PNG`` you should upgrade immediately.
+
+Before Pillow 8.0.0 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.
