Prior to 1.0.7, the `SFNT/TTF` font loader's `SfntLoader::gen` function in `tvgSfntLoader.cpp` reads `data[0] through data[3]` to identify the font type without first checking that the input buffer contains at least four bytes. Loading an undersized font directly from memory through public APIs such as `tvg::Text::load` causes an out-of-bounds read. Loading through a file path using `mmap` can mask the read because of page alignment; the memory-loading API directly exposes it. Depending on memory layout, a malformed short font may crash the consuming application or disclose adjacent heap memory. This issue is fixed in version 1.0.7.\nhttps://www.cve.org/CVERecord?id=CVE-2026-58496https://github.com/thorvg/thorvg/security/advisories/GHSA-crfw-c34f-vqrjhttps://github.com/thorvg/thorvg/commit/1dc232a33535946b5eed5fd65e993b13226da0cahttps://github.com/thorvg/thorvg/releases/tag/v1.0.7#thorvg#CVE_2026_58496#bot", "url": "https://infosec.exchange/users/cve/statuses/117515221732141179"}, {"timestamp": "2026-10-27T23:17:00Z", "date_only": false, "value": "2026-10-27T23:17:00Z", "kind": "milestone", "label": "Published", "source": "osv_ubuntu \u00b7 UBUNTU-CVE-2026-58496", "record": "UBUNTU-CVE-2026-58496", "field": "published", "metric_role": "disclosure", "metric_basis": "recorded_event"}, {"timestamp": "2026-10-27T23:17:00Z", "date_only": false, "value": "2026-10-27T23:17:00Z", "kind": "other", "label": "Updated", "source": "osv_ubuntu \u00b7 UBUNTU-CVE-2026-58496", "record": "UBUNTU-CVE-2026-58496", "field": "modified"}, {"timestamp": "2026-10-27T23:17:06.420Z", "date_only": false, "value": "2026-10-27T23:17:06.420", "kind": "milestone", "label": "Published", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-58496", "record": "FKIE_CVE-2026-58496", "field": "published", "metric_role": "disclosure", "metric_basis": "recorded_event"}, {"timestamp": "2026-10-28T15:24:56.033Z", "date_only": false, "value": "2026-10-28T15:24:56.033", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2026-58496", "record": "FKIE_CVE-2026-58496", "field": "lastModified"}], "metrics": {"as_of": "2026-10-30T15:38:25.719Z", "anchors": {"origin": {"timestamp": "2026-10-27T22:18:34.301Z", "date_only": false, "value": "2026-10-27T22:18:34.301Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-58496", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "discovery": null, "report": null, "acknowledgement": null, "disclosure": {"timestamp": "2026-10-27T22:18:34.301Z", "date_only": false, "value": "2026-10-27T22:18:34.301Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-58496", "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": 235191.418513, "hours": 65.33094958694444, "days": 2.7221228994560187, "min_seconds": 235191.418513, "max_seconds": 235191.418513, "approximate": false, "ongoing": true, "order_known": true, "batch_listing": false, "end_before_start": false, "start": {"timestamp": "2026-10-27T22:18:34.301Z", "date_only": false, "value": "2026-10-27T22:18:34.301Z", "kind": "milestone", "label": "Published", "source": "cvelistv5", "record": "CVE-2026-58496", "field": "cveMetadata.datePublished", "metric_role": "disclosure", "metric_basis": "recorded_event"}, "end": {"timestamp": "2026-10-30T15:38:25.719Z", "date_only": false, "label": "As of", "source": "Calculation clock"}}, "exploitation_to_patch": {"available": false, "missing": ["start"]}, "exploit_publication_to_patch": {"available": false, "missing": ["start"]}}}
