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: Denial of service due to use-after-free vulnerability

A flaw was found in FreeRDP. A remote attacker could exploit a use-after-free vulnerability in the xfSetWindowMinMaxInfo function. This occurs when a freed window pointer is dereferenced because the main thread concurrently deletes a window while the Remote Desktop Protocol RAIL channel thread is...

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: Denial of Service via crafted audio data in RDP

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol RDP. A remote attacker can exploit a sizet underflow vulnerability in the IMA-ADPCM and MS-ADPCM audio decoders by sending specially crafted audio data over the RDPSND audio channel. This underflow leads to a...

FreeRDP: FreeRDP: Memory corruption vulnerability allows denial of service or arbitrary code execution

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. A memory corruption vulnerability exists in the persistent cache handling. If a memory reallocation fails, an internal size variable is incorrectly updated, while the data pointer still refers to the original,...

freerdp: FreeRDP has a heap-buffer-overflow in bitmap_cache_put via OOB cacheId

A heap based buffer overflow flaw has been discovered in FreeRDP. This client-side heap out-of-bounds read/write occurs in FreeRDP's bitmap cache subsystem due to an off-by-one boundary check in bitmapcacheput. A malicious server can send a CACHEBITMAPORDER Rev1 with cacheId equal to maxCells,...

FreeRDP: FreeRDP: Information disclosure and denial of service via heap-buffer-overflow read

A flaw was found in FreeRDP, a free implementation of the Remote Desktop Protocol. This vulnerability, a heap-buffer-overflow read, exists in the winpralignedoffsetrecalloc function. A local attacker could exploit this flaw, with user interaction, to read sensitive information from memory, leadin...
