CVE-2023-44271
Published: 3 November 2023
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 |
