Description
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.26.0, a malicious RDP client can trigger a heap-buffer-overflow write in FreeRDP's server-side clipboard (cliprdr) channel by sending a CB_CLIP_CAPS PDU with a too-small capabilitySetLength. This can crash the server process (remote DoS) and may be exploitable for code execution because it corrupts heap memory. This vulnerability is fixed in 3.26.0.

Title: FreeRDP, Description: FreeRDP es una implementación gratuita del Protocolo de Escritorio Remoto. Antes de la 3.26.0, un cliente RDP malicioso puede desencadenar una escritura de desbordamiento de búfer de pila en el canal del portapapeles (cliprdr) del lado del servidor de FreeRDP al enviar una PDU CB_CLIP_CAPS con un capabilitySetLength demasiado pequeño. Esto puede bloquear el proceso del servidor (DoS remoto) y puede ser explotable para la ejecución de código porque corrompe la memoria de pila. Esta vulnerabilidad está corregida en la 3.26.0.
