The size calculation in `build_open_gop_key_points()` goes through all entries in the loop and adds `sc->ctts_data[i].count` to `sc->sample_offsets_count`. This can lead to an integer overflow resulting in a small allocation with `av_calloc()`. An attacker can cause remote code execution via a malicious mp4 file. We recommend upgrading past commit c953baa084607dd1d84c3bfcce3cf6a87c3e6e05" } ] }, "generator": { "engine": "Vulnogram 0.0.9" }, "impact": { "cvss": { "attackComplexity": "HIGH", "attackVector": "NETWORK", "availabilityImpact": "HIGH", "baseScore": 9, "baseSeverity": "CRITICAL", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "privilegesRequired": "NONE", "scope": "CHANGED", "userInteraction": "NONE", "vectorString": "CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:H/I:H/A:H", "version": "3.1" } }, "problemtype": { "problemtype_data": [ { "description": [ { "lang": "eng", "value": "CWE-122 Heap-based Buffer Overflow" } ] } ] }, "references": { "reference_data": [ { "refsource": "MISC", "url": "https://github.com/FFmpeg/FFmpeg/commit/c953baa084607dd1d84c3bfcce3cf6a87c3e6e05", "name": "https://github.com/FFmpeg/FFmpeg/commit/c953baa084607dd1d84c3bfcce3cf6a87c3e6e05" } ] }, "source": { "discovery": "INTERNAL" } }
