Doc Text:	A flaw was found in python-pillow. This flaw allows an attacker to pass controlled parameters directly into a convert function, triggering a buffer overflow in the "convert()" or "ImagingConvertTransparent()" functions in Convert.c. The highest threat to this vulnerability is to system availability. In Red Hat Quay, a vulnerable version of python-pillow is shipped with quay-registry-container, however the invoice generation feature which uses python-pillow is disabled by default. Therefore impact has been rated Moderate.	Story Points:	---

Description Guilherme de Almeida Suckevicz 2021-07-14 18:15:56 UTC

Pillow through 8.2.0 and PIL (aka Python Imaging Library) through 1.1.7 allow an attacker to pass controlled parameters directly into a convert function to trigger a buffer overflow in Convert.c.
