If a wildcard * exhausts the entire hostname string, the function reads one byte past the buffer without a bounds check, which could cause a crash.","modified":"2026-07-14T21:50:13.453365134Z","published":"2026-07-14T21:41:35.775Z","upstream":["CVE-2026-5772","EUVD-2026-21218","GHSA-6v2v-jgg9-h79w"],"database_specific":{"sources":[{"modified":"2026-06-17T10:59:37.223Z","published":"2026-04-09T22:16:36.937Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-5772","html_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-5772","database_specific":{"status":"Analyzed"},"id":"CVE-2026-5772","imported":"2026-07-14T21:22:49.240Z"},{"id":"GHSA-6v2v-jgg9-h79w","imported":"2026-07-14T21:23:00.606Z","modified":"2026-04-29T15:30:34Z","published":"2026-04-10T00:30:31Z","url":"https://api.github.com/advisories/GHSA-6v2v-jgg9-h79w","html_url":"https://github.com/advisories/GHSA-6v2v-jgg9-h79w"},{"imported":"2026-07-14T21:22:51.684Z","modified":"2026-04-10T13:52:58Z","published":"2026-04-09T21:50:04Z","url":"https://euvdservices.enisa.europa.eu/api/enisaid?id=EUVD-2026-21218","html_url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-21218","id":"EUVD-2026-21218"}],"license":"CC-BY-4.0"},"references":[{"type":"WEB","url":"https://github.com/advisories/GHSA-6v2v-jgg9-h79w"},{"type":"WEB","url":"https://github.com/wolfSSL/wolfssl/pull/10119"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-5772"}],"affected":[{"package":{"name":"wolfSSL_jll","ecosystem":"Julia","purl":"pkg:julia/wolfSSL_jll?uuid=98c43586-9870-5ae5-ab22-acc77b9bbdb5"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"5.9.2+0"}]}],"database_specific":{"source":"https://github.com/JuliaLang/SecurityAdvisories.jl/tree/generated/osv/2026/JLSEC-2026-740.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:P/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N"}]}
