{"schemaVersion":3,"id":"CVE-2026-112896","aliases":["DEBIAN-CVE-2026-112896"],"status":"published","duplicateOf":null,"title":null,"description":"Pillow is a Python imaging library. Prior to 13.0.0, Pillow's TIFF encoder can read beyond a ColorMap buffer when retained TIFF metadata has a plane size inconsistent with BitsPerSample. A small TIFF can be opened normally and then retain a crafted ColorMap that is reused when the image is saved. An application that re-encodes the attacker's TIFF with libtiff can trigger the out-of-bounds read. This can disclose heap memory in the output or crash the process. This issue is fixed in version 13.0.0.","dates":{"published":"2026-10-19T21:59:17.743Z","modified":"2026-10-19T21:59:17.743Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":8.8,"severity":"high","version":"4.0","versionLabel":"v4.0","source":"CVE.org","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N","computed":false,"selection":"backend-summary"},"metrics":[{"version":"4.0","versionLabel":"v4.0","source":"CVE.org","score":8.8,"severity":"high","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:H/SC:N/SI:N/SA:N","exploitability":null,"impact":null,"computed":false},{"version":"4.0","versionLabel":"v4.0","source":"NVD","score":8.8,"severity":"high","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/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","exploitability":null,"impact":null,"computed":false}]},"epss":{"probability":null,"percentile":null,"severity":"unknown","asOf":null,"change":{"pp":null,"baselineDate":null,"baselineScore":null},"history":[],"last30":[]},"kev":{"state":"not-listed","entries":[],"listedCount":0,"totalCatalogs":3,"catalogs":[{"source":"cisa","label":"CISA","listed":false,"entry":null},{"source":"enisa","label":"ENISA","listed":false,"entry":null},{"source":"circl","label":"CIRCL","listed":false,"entry":null}]},"ransomware":{"state":"none-recorded","sources":[]},"exploits":[],"exploitCount":0,"weaknesses":[{"id":"CWE-125","name":"Out-of-bounds Read","description":"The product reads data past the end, or before the beginning, of the intended buffer.","type":"weakness","status":"Draft","abstraction":"Base","likelihoodOfExploit":null,"url":"https://cwe.mitre.org/data/definitions/125.html"}],"affected":[{"vendor":"debian","product":"pillow","name":"pillow","label":"pillow","ecosystem":"Debian","cpePart":null,"purl":"pkg:deb/debian/pillow","purlType":"deb","versions":[{"text":"All versions","noFixRecorded":true,"fixedIn":null}],"versionsText":"All versions (No fix recorded)","eol":null,"hubHref":null},{"vendor":"python-pillow","product":"pillow","name":"Pillow","label":"pillow","ecosystem":null,"cpePart":"a","purl":null,"purlType":null,"versions":[{"text":"< 13.0.0","noFixRecorded":false,"fixedIn":null}],"versionsText":"< 13.0.0","eol":null,"hubHref":"/vendor/python-pillow/pillow"}],"affectedCount":2,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://github.com/python-pillow/Pillow/security/advisories/GHSA-pchr-8j38-3x4p","label":"github.com/python-pillow/Pillow/security/advisories/GHSA-pchr-8j38-3x4p","hostname":"github.com","tags":["X Refsource CONFIRM"]},{"url":"https://github.com/python-pillow/Pillow/commit/d03dc3c587a9b0bdc9e4304d70d59a635a87b742","label":"github.com/python-pillow/Pillow/commit/d03dc3c587a9b0bdc9e4304d70d59a635a87b742","hostname":"github.com","tags":["X Refsource MISC"]},{"url":"https://github.com/python-pillow/Pillow/releases/tag/13.0.0","label":"github.com/python-pillow/Pillow/releases/tag/13.0.0","hostname":"github.com","tags":["X Refsource MISC"]},{"url":"https://security-tracker.debian.org/tracker/CVE-2026-112896","label":"security-tracker.debian.org/tracker/CVE-2026-112896","hostname":"security-tracker.debian.org","tags":["Advisory"]}],"lineage":{"upstream":[],"downstream":[],"duplicates":[],"related":[]},"timeline":[{"kind":"published","date":"2026-10-19T21:59:17.743Z","label":"Published","detail":"Vulnerability first disclosed.","source":null}],"risk":{"score":35,"level":"medium","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-20T13:53:09.506Z","stale":false,"partial":false}}
