{"id":"CVE-2026-40489","summary":"editorconfig-core-c has incomplete fix for CVE-2023-0341","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.","aliases":["GHSA-97xg-vrcq-254h"],"modified":"2026-08-12T16:24:06.265954Z","published":"2026-04-18T01:24:57.278Z","related":["SUSE-SU-2026:22125-1","SUSE-SU-2026:2731-1","openSUSE-SU-2026:10663-1","openSUSE-SU-2026:20966-1"],"database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-121","CWE-787"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/40xxx/CVE-2026-40489.json"},"references":[{"type":"WEB","url":"https://github.com/editorconfig/editorconfig-core-c/releases/tag/v0.12.11"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/40xxx/CVE-2026-40489.json"},{"type":"ADVISORY","url":"https://github.com/editorconfig/editorconfig-core-c/security/advisories/GHSA-97xg-vrcq-254h"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-40489"},{"type":"FIX","url":"https://github.com/editorconfig/editorconfig-core-c/commit/5159be88ad50641d9843289adda791ba300421ff"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/editorconfig/editorconfig-core-c","events":[{"introduced":"0"},{"fixed":"5159be88ad50641d9843289adda791ba300421ff"},{"fixed":"0ba157eff167c1b2d1bc0c3e13975b7a73fb9d25"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"0.12.11"}],"source":["AFFECTED_FIELD","REFERENCES"]}}],"versions":["v0.12.10","v0.12.9","v0.12.8","v0.12.7","v0.12.6","v0.12.5","v0.12.4","v0.12.3","v0.12.2","v0.12.1","v0.12.0","v0.12.0-beta","v0.12.0-alpha1","v0.11.5","v0.11.4","v0.11.3","v0.11.0","v0.10.0","v0.9.1","v0.9.0","v0.8.0"],"database_specific":{"vanir_signatures":[{"target":{"file":"src/lib/ec_glob.c","function":"ec_glob"},"deprecated":false,"digest":{"function_hash":"113504869699976989321234718115873762603","length":4558},"id":"CVE-2026-40489-3621160f","signature_type":"Function","signature_version":"v1","source":"https://github.com/editorconfig/editorconfig-core-c/commit/5159be88ad50641d9843289adda791ba300421ff"},{"signature_type":"Line","signature_version":"v1","source":"https://github.com/editorconfig/editorconfig-core-c/commit/5159be88ad50641d9843289adda791ba300421ff","target":{"file":"src/lib/ec_glob.c"},"deprecated":false,"digest":{"line_hashes":["118771220304447511001250232753974064498","263396701957562860683093336295544499960","212725471622076258926958822295147843625","324446910542984109512982903483050839781","161666992118196387847668957860246513980"],"threshold":0.9},"id":"CVE-2026-40489-3646f6de"}],"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-40489.json","vanir_signatures_modified":"2026-08-12T16:24:06Z"}}],"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"}]}
