From 8.1.0 until 13.0.0, Pillow's TIFF tile and RGBA decode paths can read beyond row data produced by libtiff. In _decodeTile and the RGBA unpacker path, when Pillow and libtiff interpret duplicated PhotometricInterpretation or BitsPerSample tags differently, Pillow does not verify that the required input row fits inside the row libtiff produced, while the strip path has this validation. Loading pixels from such a crafted TIFF can expose adjacent heap data in output pixels or crash the process. This issue is fixed in version 13.0.0.\n\n## Affected\n\n- `Pillow >= 8.1.0, < 13.0.0`\n\n## Remediation\n\nRefer to the linked advisories for vendor-supplied fixes and affected version ranges.\n\n## Package advisory (CVE-2026-112404)\n\nAffected packages:\n\n- `pillow >= 8.1.0, < 13.0.0`\n\nPatched in:\n\n- `pillow 13.0.0`\n\nSource: https://osv.dev/vulnerability/GHSA-c6hw-5grf-ff96\n\n## Vendor advisories\n\n- **Red Hat VEX** · Important · affected: Exploit Intelligence, Lightspeed Core, OpenShift Lightspeed, Red Hat AI Inference Server, Red Hat Ansible Automation Platform 2, Red Hat Enterprise Linux 8, … · no fix planned: Exploit Intelligence, Lightspeed Core, OpenShift Lightspeed, Red Hat AI Inference Server, … · updated 2026-10-23 · [vex](https://security.access.redhat.com/data/csaf/v2/vex/2026/cve-2026-112404.json)","depth":"midnight","depthScore":60,"depthScoreParts":{"impact":48.4,"likelihood":0.1,"exploitation":12,"ransomware":0},"changes":[{"seq":230716,"id":"CVE-2026-112404","ts":1793204067037,"field":"exploit_available","old":"false","new":"true"},{"seq":230715,"id":"CVE-2026-112404","ts":1793204067037,"field":"cvss","old":"8.2","new":"8.8"},{"seq":227044,"id":"CVE-2026-112404","ts":1792585040916,"field":"cvss","old":"8.8","new":"8.2"}]}
