From 9.2.0 until 13.0.0, Pillow performs quadratic copying when saving a GIF with a long comment. _get_global_header() repeatedly copies portions of comment data while assembling the global header, including comments retained from an untrusted input image. An attacker can supply an image with a large GIF comment to an application that saves it as GIF. This can consume excessive CPU and delay or deny service. This issue is fixed in version 13.0.0.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-407"],"vendors":[],"products":[],"references":[{"url":"https://github.com/python-pillow/Pillow/commit/68a3fe957d8a4d552e8c69d96066d749f0614c7e","tags":[]},{"url":"https://github.com/python-pillow/Pillow/releases/tag/13.0.0","tags":[]},{"url":"https://github.com/python-pillow/Pillow/security/advisories/GHSA-fc9g-5qg7-mf45","tags":[]}],"exploitRefs":[{"url":"https://github.com/python-pillow/Pillow/commit/68a3fe957d8a4d552e8c69d96066d749f0614c7e","tags":[]},{"url":"https://github.com/python-pillow/Pillow/releases/tag/13.0.0","tags":[]},{"url":"https://github.com/python-pillow/Pillow/security/advisories/GHSA-fc9g-5qg7-mf45","tags":[]}],"hasPoc":true,"ai":null}
