Echo: rsync: security update to 3.5.0+ds1-1

medium Tenable Cloud Security Plugin ID 464077

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- 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. (CVE-2026-53788)

Solution

Update the rsync library and its related packages to version 3.5.0+ds1-1 or later.
