Short explanation
FreeRDP versions 2.0.0 before 3.32.0 contain a heap-based buffer overflow vulnerability during MP3 audio decoding.
A malicious RDP server can trigger heap overflow conditions on the client side, resulting in client crashes and security impacts.
What should be done?
- Consult the vendor advisory for updates.
- Evaluate updating to unaffected versions.
- Review compilation configuration flags.

Chain of evidence and sources
FreeRDP 2.0.0 ve 3.32.0 sürümleri arasında freerdp_dsp_decode_mp3 fonksiyonunda yığın tabanlı tampon taşması bulunmaktadır.
Açık, WITH_LAME=ON ve WITH_DSP_FFMPEG=OFF ayarlarıyla derleme yapıldığında ortaya çıkmaktadır.
Kötü amaçlı bir RDP sunucusu rdpsnd üzerinden MP3 ses göndererek istemcinin çökmesine neden olabilir.
Show the technical text from the sources
FreeRDP 2.0.0 before 3.32.0, when built with WITH_LAME=ON and WITH_DSP_FFMPEG=OFF, has a heap-based buffer overflow in freerdp_dsp_decode_mp3 because the right-channel PCM pointer is offset by a byte count treated as short elements. A malicious RDP server can send MP3 audio over rdpsnd so decoded samples cross the heap allocation, crashing the client.
