How to fix?

Upgrade Debian:unstable freerdp3 to version 3.31.0+dfsg-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream freerdp3 package and not the freerdp3 package as distributed by Debian. See How to fix? for Debian:unstable relevant fixed versions and status.

FreeRDP before 3.31.0 contains an integer overflow in the audin Apple backends when processing FramesPerPacket values from MSG_SNDIN_OPEN messages. Attackers can supply crafted FramesPerPacket values that cause AudioQueueAllocateBuffer size computation to wrap, resulting in undersized buffer allocation and potential out-of-bounds access.
