{"id":"BIT-pillow-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":["CVE-2026-112893","GHSA-j4m9-6w36-pw47"],"modified":"2026-10-29T10:45:11.354995960Z","published":"2026-10-26T05:55:54.218Z","database_specific":{"severity":"High","cpes":["cpe:2.3:a:python:pillow:*:*:*:*:*:python:*:*"]},"references":[{"type":"FIX","url":"https://github.com/python-pillow/Pillow/commit/a7416de7f3a43128179d2cf68df3240ea8dafe13"},{"type":"ARTICLE","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":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-112893"}],"affected":[{"package":{"name":"pillow","ecosystem":"Bitnami","purl":"pkg:bitnami/pillow"},"ranges":[{"type":"SEMVER","events":[{"introduced":"10.0.0"},{"fixed":"13.0.0"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/pillow/BIT-pillow-2026-112893.json"},"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/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}],"schema_version":"1.9.2"}
