{"id":"CVE-2026-112893","state":"PUBLISHED","title":"Pillow: Invalid free in FreeType glyph rendering when a stroker is active","description":"Pillow is a Python imaging library. From 10.0.0 until 13.0.0, Pillow can free an invalid glyph pointer during FreeType rendering with an active stroker. If FT_Load_Glyph fails, cleanup may call FT_Done_Glyph on an uninitialized or stale glyph variable. An attacker can supply a malformed font as untrusted bytes to an application that draws text with a nonzero stroke width, forcing the glyph-load failure path. This can corrupt memory or crash the process. This issue is fixed in version 13.0.0.","publishedAt":"2026-10-19T21:53:49.979Z","updatedAt":"2026-10-28T15:12:48.729Z","severity":{"score":8.2,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","source":"GitHub_M"},"assigner":"GitHub_M","products":["python-pillow Pillow"],"affected":[{"vendor":"python-pillow","product":"Pillow","versions":[{"version":">= 10.0.0, < 13.0.0","status":"affected"}]}],"references":["https://github.com/python-pillow/Pillow/security/advisories/GHSA-j4m9-6w36-pw47","https://github.com/python-pillow/Pillow/commit/a7416de7f3a43128179d2cf68df3240ea8dafe13","https://github.com/python-pillow/Pillow/releases/tag/13.0.0"],"weaknesses":["CWE-457","CWE-763"],"ingestedAt":"2026-10-29T20:10:43.281Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/112xxx/CVE-2026-112893.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-112893","state":"PUBLISHED","datePublished":"2026-10-19T21:53:49.979Z","dateUpdated":"2026-10-28T15:12:48.729Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-10-19T20:16:09.856Z"},"containers":{"cna":{"title":"Pillow: Invalid free in FreeType glyph rendering when a stroker is active","descriptions":[{"lang":"en","value":"Pillow is a Python imaging library.
