CVE-2026-31884 FreeRDP has a division-by-zero in ADPCM decoders when `nBlockAlign` is 0

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.24.0, division by zero in 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...

CVE-2026-31883 FreeRDP has a `size_t` underflow in ADPCM decoder leads to heap-buffer-overflow write

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.24.0, a sizet underflow in the IMA-ADPCM and MS-ADPCM audio decoders leads to heap-buffer-overflow write via the RDPSND audio channel. In libfreerdp/codec/dsp.c, the IMA-ADPCM and MS-ADPCM decoders subtract block header...
