Echo: rsync: security update to 3.5.0

high Tenable Cloud Security Plugin ID 458232

Description

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

 - rsync 3.2.5 before 3.5.0 contains a heap out-of-bounds write vulnerability that allows remote
 unauthenticated attackers to write one attacker-controlled byte past the end of a heap allocation by
 supplying a crafted files-from entry. Attackers can trigger the vulnerability against a read-only rsync
 daemon module by providing a files-from entry containing both an interior and trailing backslash, causing
 the add_implied_include() function to under-count the trailing backslash when sizing the destination
 buffer. (CVE-2026-70461)

Solution

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