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."}],"source":{"advisory":"GHSA-pwf9-v5p9-ch4f","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T18:24:55.794Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-pwf9-v5p9-ch4f","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/FreeRDP/FreeRDP/security/advisories/GHSA-pwf9-v5p9-ch4f"},{"name":"https://github.com/FreeRDP/FreeRDP/blob/5be5553e0da72178a4b94cc1ffbdace9ceb153e5/libfreerdp/codec/h264.c#L413-L427","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/FreeRDP/FreeRDP/blob/5be5553e0da72178a4b94cc1ffbdace9ceb153e5/libfreerdp/codec/h264.c#L413-L427"},{"url":"https://security.gentoo.org/glsa/202401-16","tags":["x_transferred"]}]},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2024-11-27T16:18:28.873829Z","id":"CVE-2023-40187","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-11-27T16:18:40.576Z"}}]}}
