Upgrade Debian:11

NVD Description
Note: Versions mentioned in the description apply only to the upstream qemu
package and not the qemu
package as distributed by Debian
.
See How to fix?
for Debian:11
relevant fixed versions and status.
A stack-based buffer overflow vulnerability was found in NBD server implementation in qemu before 2.11 allowing a client to request an export name of size up to 4096 bytes, which in fact should be limited to 256 bytes, causing an out-of-bounds stack write in the qemu process. If NBD server requires TLS, the attacker cannot trigger the buffer overflow without first successfully negotiating TLS.
