Description (Chinese)
FreeRDP是FreeRDP团队的一款开源的远程桌面协议（RDP）的实现。 FreeRDP 3.21.0之前版本存在安全漏洞，该漏洞源于freerdp_bitmap_decompress_planar函数在RLE解码前未验证nSrcWidth和nSrcHeight参数，可能导致堆缓冲区溢出，进而引发崩溃或任意代码执行。
Description (English)
FreeRDP is an open-source remote desktop protocol (RDP) for the FreeRDP team. The security gap in the pre-FreeRDP 3.21.0 version stems from the failure of the Freerdp bitmap decompress planar function to verify the nSrcWidth and nSrhaight parameters prior to the RLE decode, which could result in a spill over the buffer zone, which could trigger a collapse or arbitrary code execution.
