Doc Text:
A flaw was found in FreeRDP. When handling audio input on Apple platforms, an integer overflow occurs during buffer size calculations. A malicious Remote Desktop Protocol (RDP) server can exploit this by sending a specially crafted packet during session setup, causing an undersized memory allocation. This flaw can lead to a heap-based buffer overflow, potentially allowing the server to execute arbitrary code or trigger a denial of service on the client system.

Description OSIDB Bzimport 2026-10-16 01:42:34 UTC 
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.
