Hi,
I'm iperf3 maintainer and there are two CVE fixed upstream. Version
3.19.1-1 with the fix is already in unstable and testing, and Adrian Bunk
uploaded the fix for bullseye a few days ago.
This is the fix for bookworm. I have been emailing with Salvatore
Bonaccorso and both agree that DSA are not needed for this issues and
the package can go with the next bookworm point release.
Details below, and debdiff attached. I will wait for your instructions
before doing the upload.
Debian bug report:

CVE-2025-54349
| In iperf before 3.19.1, iperf_auth.c has an off-by-one error and
| resultant heap-based buffer overflow.
https://github.com/esnet/iperf/commit/42280d2292ed5f213bfcb33b2206ebcdb151ae66
patch:
https://github.com/esnet/iperf/commit/42280d2292ed5f213bfcb33b2206ebcdb151ae66.patch
This patch fails to apply but it is easy to do it by hand.

| failure and application exit upon a malformed authentication
| attempt.

patch:
https://github.com/esnet/iperf/commit/de932ea16bc959f839d28d370f0602de52c5def1.patch
