AI-Generated

FreeRDP versions prior to 3.31.0 are vulnerable to an out-of-bounds read due to improper buffer bounds validation in the rdpdr_dump_packet function. A malicious RDP server can exploit this vulnerability by sending a specially crafted RDPDR packet, potentially leading to client crashes or sensitive information leakage in logs. Organizations using FreeRDP should prioritize patching to mitigate the risk of exploitation.

Original NVD Description

FreeRDP before 3.31.0 contains an out-of-bounds read vulnerability in the rdpdr_dump_packet function due to 32-bit unsigned integer wraparound in buffer bounds validation. A malicious RDP server can send a crafted RDPDR packet with computerNameLen set to 0xFFFFFFF0 to bypass bounds checks and trigger memory reads past the packet buffer, causing client crashes or heap disclosure in logs.
