{"id":"DEBIAN-CVE-2026-40489","details":"editorconfig-core-c  is an EditorConfig core library for use by plugins supporting EditorConfig parsing. Versions up to and including 0.12.10 have a stack-based buffer overflow in ec_glob() that allows an attacker to crash any application using libeditorconfig by providing a specially crafted directory structure and .editorconfig file. This is an incomplete fix for CVE-2023-0341. The pcre_str buffer was protected in 0.12.6 but the adjacent l_pattern[8194] stack buffer received no equivalent protection. On Ubuntu 24.04, FORTIFY_SOURCE converts the overflow to SIGABRT (DoS). Version 0.12.11 contains an updated fix.","modified":"2026-09-14T17:03:11.270778324Z","published":"2026-04-18T02:16:11.827Z","upstream":["CVE-2026-40489"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-40489"}],"affected":[{"package":{"name":"editorconfig-core","ecosystem":"Debian:12","purl":"pkg:deb/debian/editorconfig-core?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.12.10+~0.17.1-1","0.12.10+~0.17.1-2","0.12.10+~0.17.1-3","0.12.6-0.1","0.12.7-0.1","0.12.9+~0.15.1-1","0.12.9+~0.17.1-1","0.12.9+~0.17.1-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-40489.json"}},{"package":{"name":"editorconfig-core","ecosystem":"Debian:13","purl":"pkg:deb/debian/editorconfig-core?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.12.10+~0.17.1-1","0.12.10+~0.17.1-2","0.12.10+~0.17.1-3","0.12.9+~0.17.1-1","0.12.9+~0.17.1-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-40489.json"}},{"package":{"name":"editorconfig-core","ecosystem":"Debian:14","purl":"pkg:deb/debian/editorconfig-core?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.12.10+~0.17.1-1","0.12.10+~0.17.1-2","0.12.10+~0.17.1-3","0.12.9+~0.17.1-1","0.12.9+~0.17.1-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-40489.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
