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

high Tenable Self-Hosted Container Security Plugin ID 463149

Description

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

 - rsync daemon 2.0.0 before 3.5.0 contains a denial of service vulnerability that allows unauthenticated
 remote attackers to exhaust daemon connection slots by stalling the handshake process before or after
 module selection without triggering the I/O timeout. Attackers can open many simultaneous connections and
 trickle data at the minimum rate to avoid timeout, or stall entirely before module selection where no
 timeout applies, consuming all available connection slots and denying service to legitimate clients.
 (CVE-2026-70464)

Solution

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