Affected versions of the 3.x beta branch are subject to a Use-After-Free issue in the `avc420_ensure_buffer` and `avc444_ensure_buffer` functions. If the value of `piDstSize[x]` is 0, `ppYUVDstData[x]` will be freed. However, in this case `ppYUVDstData[x]` will not have been updated which leads to a Use-After-Free vulnerability. This issue has been addressed in version 3.0.0-beta3. Users of the 3.x beta releases are advised to upgrade. There are no known workarounds for this vulnerability."}], "lastModified": "2024-01-12T13:15:10.897", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:freerdp:freerdp:3.0.0:beta1:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "D8720D61-0B0D-40ED-B3C4-B452D83BF3C2"}, {"criteria": "cpe:2.3:a:freerdp:freerdp:3.0.0:beta2:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "18A75D02-0E7A-4AAF-8E23-0CDCB1733FEA"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
