This update removes the usage of the C (Credential) flag for the binfmt_misc registration within the qemu-user package, as it allowed for privilege escalation when running a suid/sgid binary under qemu-user. This means suid/sgid foreign-architecture binaries are not running with elevated privileges under qemu-user anymore. If you relied on this behavior of qemu-user in the past (running suid/sgid foreign-arch binaries), this will require changes to your deployment.

In Bookworm the affected packages are qemu-user-static (and qemu-user-binfmt) instead of qemu-user.

Additionally, two security issues were fixed the in SR-IOV support of QEMU system emulation.
