Debian 11: DLA-4240-1 important: redis DoS and remote code execution

* CVE-2025-32023: An authenticated user may have used a
specially-crafted string to trigger a stack/heap out-of-bounds
write during hyperloglog operations, potentially leading to a
remote code execution vulnerability. Installations that used Redis'
ACL system to restrict hyperloglog HLL commands are unaffected by
this issue.

* CVE-2025-48367: An unauthenticated connection could have caused
repeated IP protocol errors, leading to client starvation and
ultimately become a Denial of Service (DoS) attack.

For Debian 11 bullseye, these problems have been fixed in version
5:6.0.16-1+deb11u7.

We recommend that you upgrade your redis packages.
