Name of the Vulnerable Software and Affected Versions FreeRDP versions prior to 3.24.2
Description FreeRDP is a free implementation of the Remote Desktop Protocol. The progressive decompress tile upgrade() function detects a mismatch through progressive rfx quant cmp equal() but only emits a warning, allowing execution to continue. A wrapped value (247) is used as a shift exponent, leading to undefined behavior and a loop of approximately 80 billion iterations, resulting in a CPU denial of service (DoS).
Recommendations Update to version 3.24.2 or later.
