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.

Notes

Author Note
Priority reason: Only consumes memory when very long strings are used as text input
mdeslaur upstream patch adds MAX_STRING_LENGTH which defaults to 1,000,000 limit.
