FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to version 3.24.2, progressive_decompress_tile_upgrade() detects a mismatch via progressive_rfx_quant_cmp_equal() but only emits WLog_WARN, execution continues. The wrapped value (247) is used as a shift exponent, causing undefined behavior and an approximately 80 billion iteration loop (CPU DoS). This issue has been patched in version 3.24.2.
AnalysisAI
FreeRDP versions prior to 3.24.2 contain an integer overflow vulnerability in the progressive_decompress_tile_upgrade() function that allows unauthenticated remote attackers to cause a denial of service through CPU exhaustion. When processing malformed Remote Desktop Protocol (RDP) streams, a wrapped integer value (247) is incorrectly used as a bit-shift exponent, triggering undefined behavior and creating an approximately 80 billion iteration loop that consumes CPU resources. …
