| Package | Affected versions | Patched versions |
|---|---|---|
| php | ≥ 7.2.0, ≤ 7.2.27≥ 7.3.0, ≤ 7.3.14≥ 7.4.0, ≤ 7.4.2 |
In PHP versions 7.2.x below 7.2.28, 7.3.x below 7.3.15 and 7.4.x below 7.4.3, when using file upload functionality, if upload progress tracking is enabled, but session.upload_progress.cleanup is set to 0 (disabled), and the file upload fails, the upload procedure would try to clean up data that does not exist and encounter null pointer dereference, which would likely lead to a crash.
