freerdp: FreeRDP has a division-by-zero in ADPCM decoders when `nBlockAlign` is 0

A division by zero flaw has been discovered in FreeRDP. This division by zero exists in the MS-ADPCM and IMA-ADPCM decoders when nBlockAlign is 0, leading to a crash. In libfreerdp/codec/dsp.c, both ADPCM decoders use size % blocksize where blocksize = context-common.format.nBlockAlign. The...

freerdp: FreeRDP has an out-of-bounds read in ADPCM decoders due to missing predictor/step_index bounds checks

An out of bounds read flaw has been discovered in FreeRDP. This out-of-bounds read exists in the MS-ADPCM and IMA-ADPCM decoders due to unchecked predictor and stepindex values from input data. An attacker may be able to leverage this weakness to leak global data...

FreeRDP: FreeRDP: Information disclosure via heap memory out of bounds read

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. A remote attacker could exploit a vulnerability where pixel data from adjacent heap memory is rendered to the screen. This can lead to the disclosure of sensitive data to the attacker...

freerdp: FreeRDP: Denial of Service via double free vulnerability during disconnect

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. This double free vulnerability occurs during the cleanup process when a remote desktop session disconnects. Specifically, if a title allocation fails, a pointer to an application window is freed but not removed fro...
