{"id":"DEBIAN-CVE-2026-42144","details":"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.","modified":"2026-09-14T17:03:36.340561344Z","published":"2026-05-04T18:16:31.830Z","upstream":["CVE-2026-42144"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-42144"}],"affected":[{"package":{"name":"cimg","ecosystem":"Debian:12","purl":"pkg:deb/debian/cimg?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.2.1+dfsg-1","3.2.1+dfsg-2","3.5.0+dfsg-1","3.5.2+dfsg-1","3.5.2+dfsg-2","4.0.4+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-42144.json"}},{"package":{"name":"cimg","ecosystem":"Debian:13","purl":"pkg:deb/debian/cimg?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.5.2+dfsg-1+deb13u1"}]}],"versions":["3.5.2+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-42144.json"}},{"package":{"name":"cimg","ecosystem":"Debian:14","purl":"pkg:deb/debian/cimg?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.5.2+dfsg-2"}]}],"versions":["3.5.2+dfsg-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-42144.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:H"}]}
