Prior to 4.7.0.1, the XER tokenizer NT() in asn1crt/asn1crt_encoding_xer.c, which is reached by all XER decode paths, copies tag characters into a fixed char Value[100] field without a length bound and reads input and lookahead bytes without checking the buffer count. A crafted XER message with an overlong tag can overwrite the tokenizer's stack frame, while a truncated tag or unterminated processing-instruction or comment sequence can read beyond the input and may cause a CPU spin. The flaws can disclose adjacent memory, corrupt stack data, crash or hang the decoder, and potentially permit code execution. This issue is fixed in version 4.7.0.1.\nhttps://www.cve.org/CVERecord?id=CVE-2026-76077https://github.com/esa/asn1scc/security/advisories/GHSA-38q3-fg5h-wwf9https://github.com/esa/asn1scc/commit/fe6ab763bc60d8a2def4104c15414809b45fffd9https://github.com/esa/asn1scc/releases/tag/4.7.0.1#esa #asn1scc#CVE_2026_76077#bot", "url": "https://infosec.exchange/users/cve/statuses/117564891636928218"}, {"timestamp": "2026-11-05T17:18:20.830Z", "date_only": false, "value": "2026-11-05T17:18:20.830", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-76077", "record": "FKIE_CVE-2026-76077", "field": "published", "metric_role": "disclosure", "metric_basis": "recorded_event", "linked_record": true}, {"timestamp": "2026-11-05T17:18:20.830Z", "date_only": false, "value": "2026-11-05T17:18:20.830", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-76077", "record": "FKIE_CVE-2026-76077", "field": "lastModified", "linked_record": true}], "metrics": {"as_of": "2026-11-08T05:23:46.859Z", "anchors": {"origin": {"timestamp": "2026-11-05T16:49:58.765Z", "date_only": false, "value": "2026-11-05T16:49:58.765Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-76077", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "discovery": null, "report": null, "acknowledgement": null, "disclosure": {"timestamp": "2026-11-05T16:49:58.765Z", "date_only": false, "value": "2026-11-05T16:49:58.765Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-76077", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "exploit_publication": null, "exploitation": null, "patch": null}, "vendor_response_time": {"available": false, "missing": ["start", "end"]}, "time_to_exploit": {"available": false, "missing": ["end"]}, "disclosure_to_exploit": {"available": false, "missing": ["end"]}, "disclosure_to_exploit_publication": {"available": false, "missing": ["end"]}, "time_to_patch": {"available": false, "missing": ["start", "end"]}, "total_time_to_patch": {"available": false, "missing": ["start", "end"]}, "disclosure_to_patch": {"available": false, "missing": ["end"]}, "time_unpatched": {"available": true, "seconds": 218028.094217, "hours": 60.56335950472222, "days": 2.5234733126967592, "min_seconds": 218028.094217, "max_seconds": 218028.094217, "approximate": false, "ongoing": true, "order_known": true, "batch_listing": false, "end_before_start": false, "start": {"timestamp": "2026-11-05T16:49:58.765Z", "date_only": false, "value": "2026-11-05T16:49:58.765Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-76077", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "end": {"timestamp": "2026-11-08T05:23:46.859Z", "date_only": false, "label": "As of", "source": "Calculation clock"}}, "exploitation_to_patch": {"available": false, "missing": ["start"]}, "exploit_publication_to_patch": {"available": false, "missing": ["start"]}}}
