Prior to 13.0.0, Pillow's XBM header parser is vulnerable to regular-expression denial of service. In XbmImageFile._open, when an application calls Image.open() on a small crafted XBM file, XbmImagePlugin applies a backtracking expression to the attacker-controlled header before image dimensions are accepted, stalling a worker for minutes and denying service. This issue is fixed in version 13.0.0.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-1333"],"vendors":[],"products":[],"references":[{"url":"https://github.com/python-pillow/Pillow/commit/2852a3e3d568997ddec745fc800991f138878f4b","tags":[]},{"url":"https://github.com/python-pillow/Pillow/releases/tag/13.0.0","tags":[]},{"url":"https://github.com/python-pillow/Pillow/security/advisories/GHSA-xgh8-jp6q-p5x8","tags":[]}],"exploitRefs":[{"url":"https://github.com/python-pillow/Pillow/commit/2852a3e3d568997ddec745fc800991f138878f4b","tags":[]},{"url":"https://github.com/python-pillow/Pillow/releases/tag/13.0.0","tags":[]},{"url":"https://github.com/python-pillow/Pillow/security/advisories/GHSA-xgh8-jp6q-p5x8","tags":[]}],"hasPoc":true,"ai":null}
