Description (English)
FreeRDP is an open-source remote desktop protocol (RDP) for the FreeRDP team. FreeRDP 3.21.0 contains a security loophole that originates from the Clear decompress function in ClearCodec, which does not verify the target rectangle, which may lead to cross-border reading and writing, thus triggering a flood of buffer zones, causing a collapse or arbitrary code execution.
