CVE-2026-63633

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.28.0, freerdpdspdecodeopus in libfreerdp/codec/dsp.c calls StreamEnsureRemainingCapacity on context-common.buffer even though opusdecode writes decoded PCM into the caller-supplied out stream. A malicious RDP server that...

CVE-2026-63117

FreeRDP is a free implementation of the Remote Desktop Protocol. Prior to 3.28.0, an authenticated RDP client can advertise DVI ADPCM with nBlockAlign equal to 8 and nChannels equal to 2 to make the bs calculation in rdpsndserverselectformat in channels/rdpsnd/server/rdpsndmain.c equal zero. The...
