From 5.1.0 until 13.0.0, Pillow can enter an infinite loop while rewriting PDF pages. PdfParser.rewrite_pages() follows Parent relationships without detecting a cycle in the page tree. An attacker can supply a cyclic PDF to an application that appends an image to that PDF. This can hold the worker at full CPU and deny service. This issue is fixed in version 13.0.0.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-835"],"vendors":[],"products":[],"references":[{"url":"https://github.com/python-pillow/Pillow/commit/b3ebf20c694f2f12537a629c30229a1d5a53f777","tags":[]},{"url":"https://github.com/python-pillow/Pillow/releases/tag/13.0.0","tags":[]},{"url":"https://github.com/python-pillow/Pillow/security/advisories/GHSA-f2g6-542v-9j58","tags":[]}],"exploitRefs":[{"url":"https://github.com/python-pillow/Pillow/commit/b3ebf20c694f2f12537a629c30229a1d5a53f777","tags":[]},{"url":"https://github.com/python-pillow/Pillow/releases/tag/13.0.0","tags":[]},{"url":"https://github.com/python-pillow/Pillow/security/advisories/GHSA-f2g6-542v-9j58","tags":[]}],"hasPoc":true,"ai":null}
