{"id":"CVE-2026-112893","summary":"Pillow: Invalid free in FreeType glyph rendering when a stroker is active","details":"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.","aliases":["GHSA-j4m9-6w36-pw47"],"modified":"2026-10-21T09:40:08.354927786Z","published":"2026-10-19T21:53:49.979Z","database_specific":{"unresolved_ranges":[{"extracted_events":[{"strategy":"StringRangeExpression","range":[{"introduced":"10.0.0"},{"fixed":"13.0.0"}],"source":"AFFECTED_FIELD"}]},{"extracted_events":[{"range":[{"fixed":"13.0.0"}],"source":"DESCRIPTION"}]}],"cna_assigner":"GitHub_M","cwe_ids":["CWE-457","CWE-763"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/112xxx/CVE-2026-112893.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/112xxx/CVE-2026-112893.json"},{"type":"FIX","url":"https://github.com/python-pillow/Pillow/commit/a7416de7f3a43128179d2cf68df3240ea8dafe13"},{"type":"WEB","url":"https://github.com/python-pillow/Pillow/releases/tag/13.0.0"},{"type":"ADVISORY","url":"https://github.com/python-pillow/Pillow/security/advisories/GHSA-j4m9-6w36-pw47"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-112893"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/python-pillow/pillow","events":[{"introduced":"0"},{"fixed":"a7416de7f3a43128179d2cf68df3240ea8dafe13"},{"fixed":"293218ad059d994baf1777d882911bed6a49704a"}],"database_specific":{"extracted_events":[{"range":[{"fixed":"a7416de7f3a43128179d2cf68df3240ea8dafe13"}],"source":"REFERENCES_COMMIT"},{"range":[{"fixed":"293218ad059d994baf1777d882911bed6a49704a"}],"source":"REFERENCES_TAG","original_tag":"13.0.0"}]}}],"versions":["12.3.0","12.2.0","12.1.0","12.0.0","11.3.0","11.2.1","11.1.0","11.0.0","10.4.0","10.3.0","10.2.0","10.1.0","10.0.0","9.5.0","9.4.0","9.3.0","9.2.0","9.1.0","9.0.0","8.4.0","8.3.0","8.2.0","8.1.0","8.0.0","7.2.0","7.1.0","7.0.0","6.2.0","6.1.0","6.0.0","5.4.0","5.3.0","5.2.0","5.1.0","5.0.0","4.3.0","4.2.0","4.1.0","4.0.0","4.0.0a","3.4.0","3.3.0","3.2.0","3.1.0","3.1.0-rc1","2.9.0","2.9.0.dev2","2.9.0.dev1","2.9.0.dev0","2.8.1","2.8.0","2.7.0","2.5.0","2.3.0","2.2.1","2.2.0","2.1.0","2.0.0","1.7.8","1.7.7","1.2","1.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-112893.json","vanir_signatures":[{"signature_version":"v1","source":"https://github.com/python-pillow/pillow/commit/a7416de7f3a43128179d2cf68df3240ea8dafe13","target":{"file":"src/_imagingft.c"},"deprecated":false,"digest":{"line_hashes":["103995457516083267202887685954372835498","32627880924917568965801668774650903981","74266789401567648211073070624103540115","197981431645359471179514602934191773175","116761579004992527202820398443444696017","52020544686571475984600386074731809523","161843099776387101080475220460721563442","34623731496623128151333022586594101647","326699936067726793209840522691241867824","271537527962711622809171344020791164358","194815329363439569411234115616725844730","259080024668944424682920391579393045404"],"threshold":0.9},"id":"CVE-2026-112893-9312bdbb","signature_type":"Line"},{"signature_version":"v1","source":"https://github.com/python-pillow/pillow/commit/a7416de7f3a43128179d2cf68df3240ea8dafe13","target":{"file":"src/_imagingft.c","function":"font_render_impl"},"deprecated":false,"digest":{"function_hash":"43866863385297283531700721972227882874","length":7440},"id":"CVE-2026-112893-e1db82f8","signature_type":"Function"}],"vanir_signatures_modified":"2026-10-21T09:40:08Z"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"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"}]}
