Lifecycle Timeline
3Description
FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.24.0, there is an out-of-bounds read in MS-ADPCM and IMA-ADPCM decoders due to unchecked predictor and step_index values from input data. This vulnerability is fixed in 3.24.0.
Analysis
FreeRDP versions prior to 3.24.0 contain an out-of-bounds read vulnerability in MS-ADPCM and IMA-ADPCM audio decoders that allows unauthenticated remote attackers to read sensitive information from process memory. The vulnerability affects all FreeRDP installations using these audio codecs; an attacker can trigger the flaw by providing specially crafted audio data during RDP session establishment, potentially disclosing confidential data such as credentials or session tokens without requiring privileges or interaction beyond basic RDP connection initiation.
