{"id":"JLSEC-2026-747","summary":"PKCS#12 MAC verification uses an attacker-controlled comparison length, weakening the integrity...","details":"PKCS#12 MAC verification uses an attacker-controlled comparison length, weakening the integrity check on the MAC and allowing a mismatched MAC to be accepted. The PKCS#12 verify path compared the locally computed HMAC against the MAC parsed from the PKCS#12 structure using a length taken directly from the attacker-supplied input, without first verifying that it equals the length of the digest actually produced by the configured algorithm. A truncated or zero-length stored MAC could therefore be accepted, defeating the integrity protection of the MAC.","modified":"2026-07-18T00:02:22.653833322Z","published":"2026-07-14T21:41:35.775Z","upstream":["CVE-2026-6329","GHSA-r98j-g9p3-fcgm","EUVD-2026-39571"],"database_specific":{"sources":[{"html_url":"https://nvd.nist.gov/vuln/detail/CVE-2026-6329","database_specific":{"status":"Analyzed"},"id":"CVE-2026-6329","imported":"2026-07-17T22:35:25.336Z","modified":"2026-06-27T19:51:09.053Z","published":"2026-06-25T22:17:02.757Z","url":"https://services.nvd.nist.gov/rest/json/cves/2.0?cveId=CVE-2026-6329"},{"published":"2026-06-26T00:32:06Z","url":"https://api.github.com/advisories/GHSA-r98j-g9p3-fcgm","html_url":"https://github.com/advisories/GHSA-r98j-g9p3-fcgm","id":"GHSA-r98j-g9p3-fcgm","imported":"2026-07-17T22:35:25.503Z","modified":"2026-06-27T21:31:35Z"},{"url":"https://euvdservices.enisa.europa.eu/api/enisaid?id=EUVD-2026-39571","html_url":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-39571","id":"EUVD-2026-39571","imported":"2026-07-17T22:35:35.279Z","modified":"2026-06-26T10:22:21Z","published":"2026-06-25T21:02:45Z"}],"license":"CC-BY-4.0"},"references":[{"type":"WEB","url":"https://github.com/advisories/GHSA-r98j-g9p3-fcgm"},{"type":"WEB","url":"https://github.com/wolfSSL/wolfssl/pull/10192"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-6329"},{"type":"WEB","url":"https://www.wolfssl.com/docs/security-vulnerabilities"},{"type":"WEB","url":"https://www.wolfssl.com/docs/security-vulnerabilities/"}],"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-2026-747.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:P/PR:L/UI:N/VC:N/VI:H/VA:N/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"}]}
