FreeRDP can be tricked into writing past memory via audio data

CVE-2026-111380 · published 1 day ago
Summary

FreeRDP versions from 3.29.0 up to but not including 3.32.0 have a flaw in the way they calculate the size of an audio buffer on macOS and iOS. A specially crafted remote desktop server can cause the client to allocate a buffer that is too small, leading to memory corruption. Update FreeRDP to version 3.32.0 or later to fix the issue.

What to do
  • Update freerdp freerdp to version 3.32.0 or later.

Original advisory text
FreeRDP 3.29.0 before 3.32.0 Heap Overflow via audin Apple Backends
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.
