{"id":"DEBIAN-CVE-2026-32249","details":"Vim is an open source, command line text editor. From 9.1.0011 to before 9.2.0137, Vim's NFA regex compiler, when encountering a collection containing a combining character as the endpoint of a character range (e.g. [0-0\\u05bb]), incorrectly emits the composing bytes of that character as separate NFA states. This corrupts the NFA postfix stack, resulting in NFA_START_COLL having a NULL out1 pointer. When nfa_max_width() subsequently traverses the compiled NFA to estimate match width for the look-behind assertion, it dereferences state-\u003eout1-\u003eout without a NULL check, causing a segmentation fault. This vulnerability is fixed in 9.2.0137.","modified":"2026-09-29T13:03:40.479044207Z","published":"2026-03-12T20:16:05.523Z","upstream":["CVE-2026-32249"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-32249"}],"affected":[{"package":{"name":"vim","ecosystem":"Debian:13","purl":"pkg:deb/debian/vim?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2:9.1.1230-2","2:9.1.1385-1","2:9.1.1766-1","2:9.1.1829-1","2:9.1.1846-1","2:9.1.1882-1","2:9.1.2103-1","2:9.1.2141-1","2:9.2.0119-1","2:9.2.0136-1","2:9.2.0218-1","2:9.2.0315-1","2:9.2.0338-1","2:9.2.0355-1","2:9.2.0428-1","2:9.2.0461-1","2:9.2.0524-1","2:9.2.0782-1","2:9.2.0858-1"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-32249.json"}},{"package":{"name":"vim","ecosystem":"Debian:14","purl":"pkg:deb/debian/vim?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:9.2.0218-1"}]}],"versions":["2:9.1.1230-2","2:9.1.1385-1","2:9.1.1766-1","2:9.1.1829-1","2:9.1.1846-1","2:9.1.1882-1","2:9.1.2103-1","2:9.1.2141-1","2:9.2.0119-1","2:9.2.0136-1"],"ecosystem_specific":{"urgency":"unimportant"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-32249.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:N/A:H"}]}
