{"id":"JLSEC-2026-117","details":"GNU Bison before 3.5.4 allows attackers to cause a denial of service (application crash). NOTE: there is a risk only if Bison is used with untrusted input, and an observed bug happens to cause unsafe behavior with a specific compiler/architecture. The bug reports were intended to show that a crash may occur in Bison itself, not that a crash may occur in code that is generated by Bison.","modified":"2026-07-18T00:01:29.478087773Z","published":"2026-04-15T19:26:36.482Z","upstream":["CVE-2020-14150"],"database_specific":{"license":"CC-BY-4.0","sources":[{"database_specific":{"status":"Modified"},"id":"CVE-2020-14150","imported":"2026-07-17T21:11:07.505Z","modified":"2026-06-17T02:54:17.900Z","published":"2020-06-15T17:15:10.450Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2020-14150","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2020-14150"}]},"references":[{"type":"WEB","url":"https://bugs.gentoo.org/717936"},{"type":"WEB","url":"https://lists.gnu.org/archive/html/info-gnu/2020-04/msg00000.html"}],"affected":[{"package":{"name":"Bison_jll","ecosystem":"Julia","purl":"pkg:julia/Bison_jll?uuid=0f48145f-aea8-549d-8864-7f251ac1e6d0"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.8.2+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-117.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V2","score":"AV:L/AC:L/Au:N/C:N/I:N/A:P"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H"}]}
