FreeRDP 缓冲区错误漏洞

FreeRDP is an open-source RDP protocol implementation developed by the FreeRDP team. Versions of FreeRDP prior to 3.24.0 contained a buffer error vulnerability. This vulnerability stemmed from a heap buffer overflow in the YUV-to-RGB conversion process implemented by AVC420/AVC444, which could...

freerdp: FreeRDP heap-buffer-overflow

A heap based buffer overflow has been discovered in FreeRDP. This heap out-of-bounds read occurs in the smartcard SetAttrib path when cbAttrLen does not match the actual NDR buffer length...

freerdp: FreeRDP heap-buffer-overflow

A heap based buffer overflow has been discovered in FreeRDP. In affected versions the URBDRC client does not perform bounds checking on server‑supplied MSUSBINTERFACEDESCRIPTOR values and uses them as indices in libusbudevcompletemsconfigsetup, causing an out‑of‑bounds read...
