Prior to 13.0.0 on Windows, src/PIL/WmfImagePlugin.py passes unchecked 32-bit WMF or EMF dimensions to the native drawwmf handler in src/display.c. The handler sizes a DIB allocation from 16-bit-truncated bcWidth and bcHeight fields but copies pixel data using the original full dimensions. A crafted wide, short metafile can pass the pixel-count decompression-bomb check and make the Windows-only renderer read beyond the heap buffer, potentially disclosing memory or crashing the process. This issue is fixed in version 13.0.0.\nhttps://www.cve.org/CVERecord?id=CVE-2026-96644https://github.com/python-pillow/Pillow/security/advisories/GHSA-9v9v-9qvf-h2hjhttps://github.com/python-pillow/Pillow/pull/10120https://github.com/python-pillow/Pillow/commit/4cf46bee338304c5c8968fd7f132ba0d40c428b7https://github.com/python-pillow/Pillow/releases/tag/13.0.0#python-pillow
