{"id":"CVE-2026-112397","published":"2026-10-19T22:17:06.970","lastModified":"2026-10-19T22:17:06.970","description":"Pillow is a Python imaging library. Prior to 13.0.0, Pillow's ImageMorph.MorphOp.apply() can access memory before a row buffer for a zero-width image. PPM and PGM input can create an image with width zero, and the native morphology routine indexes outrow[width - 1] without rejecting that geometry. An attacker can supply such an image to an application that applies a morphology operation. This can crash the process. This issue is fixed in version 13.0.0.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-787"],"vendors":[],"products":[],"references":[{"url":"https://github.com/python-pillow/Pillow/commit/18f7c0dfee93063c51db6ed0ca8c4da2999dcb64","tags":[]},{"url":"https://github.com/python-pillow/Pillow/releases/tag/13.0.0","tags":[]},{"url":"https://github.com/python-pillow/Pillow/security/advisories/GHSA-58r4-6rv3-gfh8","tags":[]},{"url":"https://github.com/python-pillow/Pillow/security/advisories/GHSA-58r4-6rv3-gfh8","tags":[]}],"exploitRefs":[{"url":"https://github.com/python-pillow/Pillow/commit/18f7c0dfee93063c51db6ed0ca8c4da2999dcb64","tags":[]},{"url":"https://github.com/python-pillow/Pillow/releases/tag/13.0.0","tags":[]},{"url":"https://github.com/python-pillow/Pillow/security/advisories/GHSA-58r4-6rv3-gfh8","tags":[]},{"url":"https://github.com/python-pillow/Pillow/security/advisories/GHSA-58r4-6rv3-gfh8","tags":[]}],"hasPoc":true,"ai":null}
