9.0.1#
Security#
This release addresses several security problems.
CVE-2022-24303: Temp image removal#
If the path to the temporary directory on Linux or macOS
contained a space, this would break removal of the temporary image file after
im.show()
(and related actions), and potentially remove an unrelated file. This
has been present since PIL.
CVE-2022-22817: Restrict lambda expressions#
While Pillow 9.0 restricted top-level builtins available to
PIL.ImageMath.eval()
, it did not prevent builtins
available to lambda expressions. These are now also restricted.
Other Changes#
Pillow 9.0 added support for xdg-open
as an image viewer, but there have been
reports that the temporary image file was removed too quickly to be loaded into the
final application. A delay has been added.
