CVE-2023-44271 (https://github.com/python-pillow/Pillow/pull/7244):

An issue was discovered in Pillow before 10.0.0. It is a Denial of Service that uncontrollably allocates memory to process a given task, potentially causing a service to crash by having it run out of memory. This occurs for truetype in ImageFont when textlength in an ImageDraw instance operates on a long text argument.

Patch: https://github.com/python-pillow/Pillow/commit/1fe1bb49c452b0318cad12ea9d97c3bef188e9a7
