Debian 11 rsync Critical Local Escalation Denial of Service DLA-4591-1

Several vulnerabilities were discovered in rsync, a fast, versatile,
remote (and local) file-copying tool, which may result in local
privilege escalation, bypass of intended access restrictions, remote
memory disclosure to an authenticated daemon peer or denial of service.


For Debian 11 bullseye, these problems have been fixed in version
3.2.3-4+deb11u4.

We recommend that you upgrade your rsync packages.
