NVD Description

Note: Versions mentioned in the description apply only to the upstream rsync package and not the rsync package as distributed by Debian. See How to fix? for Debian:11 relevant fixed versions and status.

rsync before 3.5.0 contains a newline injection vulnerability in the name-converter uid/gid mapping interface that allows local attackers to forge protocol messages by creating user or group names containing newline characters. Attackers can inject malicious newline characters into names communicated over the pipe-based line-oriented protocol to cause the rsync daemon to process attacker-influenced data as legitimate protocol input, corrupting uid/gid mapping logic.
