Several vulnerabilities were discovered in rsync, a fast, versatile, remote (and local) file-copying tool, which could result in local privilege escalation, bypass of intended access restrictions, information disclosure, denial of service or the execution of arbitrary code.

Details can be found at https://download.samba.org/pub/rsync/NEWS#3.5.0

For the stable distribution (trixie), these problems have been fixed in version 3.5.0+ds1-0+deb13u1.

We recommend that you upgrade your rsync packages.
