The line buffer is sized as the image width times the channel count with no overflow check, so a negative or very large count requests an excessive allocation. When it fails, Imager's allocator calls exit(3).\n\nPassing an untrusted raw_datachannels value to Imager->read() triggers an uncatchable exit.","published":"2026-10-01T14:17:20.000Z","lastModified":"2026-10-08T13:17:42.000Z","status":"Analyzed","sourceIdentifier":"9b29abf9-4ab0-4765-b253-1875cd9b441e","cvss":{"version":"3.1","score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-190","CWE-789"],"affected":["tonycoz/imager"],"epss":{"score":0.00392,"percentile":0.33203,"date":"2026-10-27","history":[{"date":"2026-10-02","score":0.00392,"percentile":0.30999}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (0.39%).
