When config_input() allocates the points traversal stack based on initial frame dimensions and a subsequent larger frame is processed, filter_frame() performs flood-fill neighbor pushes beyond the original allocation boundary, resulting in heap corruption and process crash with potential for code execution depending on heap layout and process hardening." } ], "tags": [ "x_open-source" ], "datePublic": "2026-07-13T00:00:00.000Z", "problemTypes": [ { "descriptions": [ { "lang": "en", "cweId": "CWE-787", "description": "Out-of-bounds Write", "type": "CWE" }, { "lang": "en", "cweId": "CWE-131", "description": "Incorrect Calculation of Buffer Size", "type": "CWE" } ] } ], "affected": [ { "defaultStatus": "affected", "vendor": "FFmpeg", "product": "FFmpeg", "repo": "https://code.ffmpeg.org/FFmpeg/FFmpeg", "versions": [ { "status": "affected", "version": "3.4", "versionType": "custom", "lessThanOrEqual": "8.1.2" }, { "status": "unaffected", "version": "f186c50cf53aec20e9a29059cb22ca3f2d59201c", "versionType": "git" } ] } ], "metrics": [ { "format": "CVSS", "scenarios": [ { "lang": "en", "value": "GENERAL" } ], "cvssV4_0": { "attackVector": "LOCAL", "attackComplexity": "LOW", "attackRequirements": "PRESENT", "privilegesRequired": "NONE", "userInteraction": "PASSIVE", "vulnConfidentialityImpact": "HIGH", "subConfidentialityImpact": "NONE", "vulnIntegrityImpact": "HIGH", "subIntegrityImpact": "NONE", "vulnAvailabilityImpact": "HIGH", "subAvailabilityImpact": "NONE", "exploitMaturity": "NOT_DEFINED", "Safety": "NOT_DEFINED", "Automatable": "NOT_DEFINED", "Recovery": "NOT_DEFINED", "valueDensity": "NOT_DEFINED", "vulnerabilityResponseEffort": "NOT_DEFINED", "providerUrgency": "NOT_DEFINED", "version": "4.0", "baseSeverity": "HIGH", "baseScore": 7.3, "vectorString": "CVSS:4.0/AV:L/AC:L/AT:P/PR:N/UI:P/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N" } }, { "format": "CVSS", "scenarios": [ { "lang": "en", "value": "GENERAL" } ], "cvssV3_1": { "attackVector": "LOCAL", "attackComplexity": "LOW", "privilegesRequired": "NONE", "userInteraction": "REQUIRED", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH", "version": "3.1", "baseSeverity": "HIGH", "baseScore": 7.8, "vectorString": "CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H" } } ], "references": [ { "url": "https://code.ffmpeg.org/FFmpeg/FFmpeg/pulls/23780", "name": "Pull Request", "tags": [ "issue-tracking" ] }, { "url": "https://code.ffmpeg.org/FFmpeg/FFmpeg/commit/f186c50cf53aec20e9a29059cb22ca3f2d59201c", "name": "Patch Commit", "tags": [ "patch" ] }, { "url": "https://www.vulncheck.com/advisories/ffmpeg-vf-floodfill-out-of-bounds-write-via-filter-frame", "tags": [ "third-party-advisory" ] } ], "credits": [ { "lang": "en", "value": "Adrian Junge (vurlo)", "type": "finder" } ], "source": { "discovery": "UNKNOWN" }, "x_generator": { "engine": "vulncheck" } }, "adp": [ { "metrics": [ { "other": { "type": "ssvc", "content": { "timestamp": "2026-07-24T03:56:31.323323Z", "id": "CVE-2026-65705", "options": [ { "Exploitation": "none" }, { "Automatable": "no" }, { "Technical Impact": "total" } ], "role": "CISA Coordinator", "version": "2.0.3" } } } ], "title": "CISA ADP Vulnrichment", "providerMetadata": { "orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2026-07-24T20:10:23.166Z" } } ] } }
