Echo: rsync: security update to 3.5.0

high Tenable Self-Hosted Container Security Plugin ID 463814

Description

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

 - rsync 3.1.0 before 3.5.0 contains an authorization bypass in auth users directive parsing. The auth users
 parser uses comma-only tokenization when splitting the user list, which fails to correctly handle entries
 of the form @Group Name where the group name contains a space. The space within the group name causes the
 parser to split the entry at the space boundary, discarding the deny rule associated with the group. An
 authenticated user whose username or group membership would be denied by an @Group Name auth users entry
 can connect to a restricted module because the deny rule is silently discarded during parsing.
 (CVE-2026-70463)

Solution

Update the rsync library and its related packages to version 3.5.0 or later.
