An upper bound check issue in `dsaVerify` function allows an attacker to construct signatures that can be successfully verified by any public key, thus leading to a signature forgery attack. All places in this project that involve DSA verification of user-input signatures will be affected by this vulnerability. This issue has been patched in version 4.2.2.","published_at":"2023-10-26T14:31:35.895000Z","last_modified_at":null,"cvss_v3_score":6.5,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N","cvss_v3_severity":"MEDIUM","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-347"],"nvd_references":["https://github.com/browserify/browserify-sign/security/advisories/GHSA-x9w5-v3q2-3rhw","https://github.com/browserify/browserify-sign/commit/85994cd6348b50f2fd1b73c54e20881416f44a30","https://lists.debian.org/debian-lts-announce/2023/10/msg00040.html","https://www.debian.org/security/2023/dsa-5539","https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/6PVVPNSAGSDS63HQ74PJ7MZ3MU5IYNVZ/","https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/3HUE6ZR5SL73KHL7XUPAOEL6SB7HUDT2/"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:20:51.686626Z"},"effective_severity":"MEDIUM","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"N","value_label":"None"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"L","value_label":"Low"},{"metric":"I","name":"Integrity","value":"L","value_label":"Low"},{"metric":"A","name":"Availability","value":"N","value_label":"None"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"browserify","vendor_name":"browserify","product_slug":"browserify-sign","product_name":"browserify-sign","version_start":">= 2.6.0, <= 4.2.1","version_start_inclusive":true,"version_end":">= 2.6.0, <= 4.2.1","version_end_inclusive":true,"cpe23_uri":"cve5:browserify:browserify-sign:>= 2.6.0, <= 4.2.1:>= 2.6.0, <= 4.2.1"}],"exploit_refs":[],"news":[],"references":[{"url":"https://github.com/browserify/browserify-sign/security/advisories/GHSA-x9w5-v3q2-3rhw","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://github.com/browserify/browserify-sign/commit/85994cd6348b50f2fd1b73c54e20881416f44a30","source_type":"PATCH","tags":["patch"]},{"url":"https://lists.debian.org/debian-lts-announce/2023/10/msg00040.html","source_type":"MAILING_LIST","tags":["mailing-list"]},{"url":"https://www.debian.org/security/2023/dsa-5539","source_type":"VENDOR_ADVISORY","tags":["advisory"]},{"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/6PVVPNSAGSDS63HQ74PJ7MZ3MU5IYNVZ/","source_type":"MAILING_LIST","tags":["mailing-list"]},{"url":"https://lists.fedoraproject.org/archives/list/package-announce@lists.fedoraproject.org/message/3HUE6ZR5SL73KHL7XUPAOEL6SB7HUDT2/","source_type":"MAILING_LIST","tags":["mailing-list"]}],"timeline":[{"type":"published","at":"2023-10-26T14:31:35.895000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:30:22.759310Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:30:22.759310Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:30:22.759310Z","label":"CVSS score revised","source":"cvelistv5"}]}
