{"id":"DEBIAN-CVE-2026-59879","details":"Immutable.js provides many Persistent Immutable data structures. Prior to 4.3.9 and 5.1.8, List#set, List#setSize, List#setIn, List#updateIn, and the functional set, setIn, and updateIn mishandle an index or size in the range 2 ** 30 to 2 ** 31 in setListBounds in src/List.js, causing an empty List to enter an uncatchable infinite loop, a populated List to allocate without bound until process abort, or setSize to silently wrap large values. This issue is fixed in versions 4.3.9 and 5.1.8.","modified":"2026-08-04T05:48:36.399934771Z","published":"2026-07-08T17:17:26.370Z","upstream":["CVE-2026-59879"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-59879"}],"affected":[{"package":{"name":"node-immutable","ecosystem":"Debian:11","purl":"pkg:deb/debian/node-immutable?arch=source&distro=bullseye"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.8.2+dfsg-3","4.0.0-1","4.0.0-2","4.0.0-3","4.0.0-4","4.1.0-1","4.1.0-2","4.1.0-3","4.3.4-1","4.3.8-1","4.3.8-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-59879.json"}},{"package":{"name":"node-immutable","ecosystem":"Debian:12","purl":"pkg:deb/debian/node-immutable?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.1.0-3","4.3.4-1","4.3.8-1","4.3.8-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-59879.json"}},{"package":{"name":"node-immutable","ecosystem":"Debian:13","purl":"pkg:deb/debian/node-immutable?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.3.4-1","4.3.8-1","4.3.8-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-59879.json"}},{"package":{"name":"node-immutable","ecosystem":"Debian:14","purl":"pkg:deb/debian/node-immutable?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.3.4-1","4.3.8-1","4.3.8-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-59879.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
