Short explanation
FreeRDP from versions 3.29.0 before 3.32.0 contains a heap overflow vulnerability due to an integer overflow in Apple audin backends. A malicious RDP server can trigger memory corruption on macOS and iOS clients.
This vulnerability allows a malicious RDP server to perform a heap out-of-bounds write on vulnerable macOS and iOS clients, carrying a high severity impact.
What should be done?
- Follow official vendor advisories and updates
- Update affected versions where possible
- Restrict connections to untrusted RDP servers
Chain of evidence and sources
FreeRDP 3.29.0 ile 3.32.0 sürümleri arasında Apple audin arka uçlarında tamsayı taşması bulunmaktadır.
Kötü amaçlı bir RDP sunucusu audin Open PDU içinde FramesPerPacket değerini manipüle edebilir.
Açık, macOS ve iOS istemcilerinde heap out-of-bounds yazmaya yol açmaktadır.
Show the technical text from the sources
FreeRDP from 3.29.0 before 3.32.0 contains an integer overflow in the Apple audin backends (audin_mac.m, audin_ios.m), which compute the audio queue buffer size as FramesPerPacket * 2 * nChannels in UINT32 arithmetic, bypassing the CVE-2026-91962 fix. A malicious RDP server can send FramesPerPacket of 2^30 in the audin Open PDU to wrap the multiplication, causing undersized AudioQueueAllocateBuffer allocations and a heap out-of-bounds write in macOS and iOS clients.
