On Windows running 32-bit Python, this results in an OverflowError or MemoryError due to the 2 GB limit. However, on Linux running 64-bit Python this results in the process being terminated by the OOM killer.","dates":{"published":"2020-01-05T22:15:00.000Z","modified":"2023-03-14T07:01:09.417Z","reserved":null,"kevAdded":[],"kevDue":[]},"cvss":{"headline":{"score":null,"severity":"unknown","version":null,"versionLabel":null,"source":null,"vector":null,"computed":false,"selection":"none"},"metrics":[]},"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":[],"affected":[{"vendor":"PyPI","product":"pillow","name":"pillow","label":"pillow","ecosystem":"PyPI","cpePart":null,"purl":"pkg:pypi/pillow","purlType":"pypi","versions":[{"text":"< 6.2.2","noFixRecorded":false,"fixedIn":null}],"versionsText":"< 6.2.2","eol":null,"hubHref":null}],"affectedCount":1,"eol":{"hasEol":false,"count":0},"references":[{"url":"https://pillow.readthedocs.io/en/stable/releasenotes/6.2.2.html","label":"pillow.readthedocs.io/en/stable/releasenotes/6.2.2.html","hostname":"pillow.readthedocs.io","tags":["WEB"]},{"url":"https://usn.ubuntu.com/4272-1/","label":"usn.ubuntu.com/4272-1/","hostname":"usn.ubuntu.com","tags":["WEB"]},{"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/3DUMIBUYGJRAVJCTFUWBRLVQKOUTVX5P/","label":"lists.fedoraproject.org/archives/…","hostname":"lists.fedoraproject.org","tags":["WEB"]},{"url":"https://www.debian.org/security/2020/dsa-4631","label":"www.debian.org/security/2020/dsa-4631","hostname":"www.debian.org","tags":["WEB"]}],"lineage":{"upstream":[],"downstream":[],"duplicates":[],"related":[]},"timeline":[{"kind":"published","date":"2020-01-05T22:15:00.000Z","label":"Published","detail":"Vulnerability first disclosed.","source":null},{"kind":"modified","date":"2023-03-14T07:01:09.417Z","label":"Last modified","detail":"Vulnerability information updated.","source":null}],"risk":{"score":0,"level":"minimal","profile":"Default","thresholds":{"critical":75,"high":50,"medium":25,"low":10}},"meta":{"dataAsOf":"2026-10-21T15:14:23.595Z","stale":false,"partial":false}}
