CVE-2023-39355

FreeRDP is a free implementation of the Remote Desktop Protocol (RDP), released
under the Apache license. Versions of FreeRDP on the 3.x release branch before
beta3 are subject to a Use-After-Free in processing `RDPGFX_CMDID_RESETGRAPHICS`
packets. If `context->maxPlaneSize` is 0, `context->planesBuffer` will be freed.
However, without updating `context->planesBuffer`, this leads to a
Use-After-Free exploit vector. In most environments this should only result in a
crash. This issue has been addressed in version 3.0.0-beta3 and users of the
beta 3.x releases are advised to upgrade. There are no known workarounds for
this vulnerability.
