Description OSIDB Bzimport 2026-11-03 16:18:25 UTC 
FreeRDP 2.0.0 before 3.32.2 contains an out-of-bounds read vulnerability in freerdp_dsp_decode_gsm610 that allows malicious RDP servers to read past audio buffers by sending truncated GSM610 frames. Attackers can negotiate GSM610 on rdpsnd and send a WAVE2 message shorter than a 33- or 32-byte WAV49 frame to crash the client.
