{"identifier":"CVE-2026-42144","cve":{"id":"CVE-2026-42144","description":"CImg Library is a C++ library for image processing. Prior to commit 4ca26bc, there is an integer overflow vulnerability in the W*H*D size computation inside _load_pnm() that can bypass the memory allocation guard. A crafted PNM/PGM/PPM file with large dimension values causes the overflow to wrap around, allocating an undersized buffer and potentially triggering a heap buffer overflow. Any application using CImg to load untrusted image files is affected. This issue has been patched via commit 4ca26bc.","published":"2026-05-04T18:16:31.830000+00:00","modified":"2026-10-26T19:10:00.163000+00:00","status":"Deferred","score":6.1,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:H","cvss_version":"3.1","affected":[],"weaknesses":["CWE-190"],"references":[{"url":"https://github.com/GreycLab/CImg/commit/4ca26bce4d8c61fcd1507d5f9401b9fb1222c27d","source":"security-advisories@github.com"},{"url":"https://github.com/GreycLab/CImg/issues/478","source":"security-advisories@github.com"},{"url":"https://github.com/GreycLab/CImg/releases/tag/v.3.7.5","source":"security-advisories@github.com"},{"url":"https://github.com/GreycLab/CImg/security/advisories/GHSA-4663-63fm-44gc","source":"security-advisories@github.com"}],"kev":null,"kev_checked":true,"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:H","baseScore":6.1,"baseSeverity":"MEDIUM","attackVector":"LOCAL","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"REQUIRED","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"LOW","availabilityImpact":"HIGH"},"exploitabilityScore":1.8,"impactScore":4.2}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"timestamp":"2026-05-05T13:07:54.801471Z","id":"CVE-2026-42144","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}]},"configurations":[],"source":"nvd","retrieved_at":"2026-10-28T10:19:58.349807+00:00","exploited":false,"kev_stale":false,"products":[],"priority":{"label":"Assess exposure and vendor guidance","reasons":["No higher-priority signal is available in the current stored evidence."]},"epss":{"probability":0.00142,"percentile":0.03502,"date":"2026-10-29","stale":false},"version_assessment":null},"news":[],"campaigns":[],"domains":[{"domain":"github.com","source_url":"https://github.com/GreycLab/CImg/commit/4ca26bce4d8c61fcd1507d5f9401b9fb1222c27d","investigate_url":"https://investigate.aeglixmind.com/#github.com"}],"arsenal_url":"https://arsenal.aeglixmind.com/?cve=CVE-2026-42144","catalog_url":"https://cves.aeglixmind.com/cve/CVE-2026-42144","research_url":"https://investigate.aeglixmind.com/research/cve/CVE-2026-42144","coverage":{"news_candidates_checked":0,"campaign_candidates_checked":0,"bounded":false,"notice":"Exact CVE mentions in stored public excerpts and reviewed campaign content only.
