This is unrelated to CWE-676. It may write beyond the bounds of the destination buffer when attempting to write a padded, thousands-separated string representation of a number, if the buffer is allocated the exact size required to represent that number as a string. For example, 1,234,567 (with padding to 13) overflows by two bytes.","published_at":"2023-02-03T00:00:00Z","last_modified_at":"2026-10-14T23:17:15.260000Z","cvss_v3_score":9.8,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","cvss_v3_severity":"CRITICAL","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":"none","ssvc_automatable":true,"ssvc_technical_impact":"total","cwes":["CWE-787"],"nvd_references":["https://sourceware.org/bugzilla/show_bug.cgi?id=30068","http://www.openwall.com/lists/oss-security/2023/02/10/1","https://security.netapp.com/advisory/ntap-20230302-0010/"],"vuln_status":"Modified","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":"2026-10-14T23:59:09.254433Z"},"effective_severity":"CRITICAL","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":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"H","value_label":"High"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"gnu","vendor_name":"gnu","product_slug":"glibc","product_name":"glibc","version_start":"2.37","version_start_inclusive":true,"version_end":"2.37","version_end_inclusive":true,"cpe23_uri":"cpe:2.3:a:gnu:glibc:2.37:*:*:*:*:*:*:*"}],"exploit_refs":[],"news":[],"references":[{"url":"https://sourceware.org/bugzilla/show_bug.cgi?id=30068","source_type":"MISC","tags":[]},{"url":"http://www.openwall.com/lists/oss-security/2023/02/10/1","source_type":"MAILING_LIST","tags":["mailing-list"]},{"url":"https://security.netapp.com/advisory/ntap-20230302-0010/","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2023-02-03T00:00:00Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:27:07.118971Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:27:07.118971Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:27:07.118971Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"ssvc_changed","at":"2026-06-29T01:27:25.549714Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:27:25.549714Z","label":"SSVC decision revised","source":"vulnrichment"},{"type":"ssvc_changed","at":"2026-06-29T01:27:25.549714Z","label":"SSVC decision revised","source":"vulnrichment"}]}
