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

high Tenable Cloud Security Plugin ID 460411

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 a signed integer overflow vulnerability in the I/O timeout
 implementation that allows attackers to permanently disable connection timeouts by injecting
 MSG_IO_TIMEOUT messages carrying non-positive (zero or negative) values. Attackers can craft malicious
 MSG_IO_TIMEOUT messages that cause the timeout variable to wrap to a non-positive value, preventing the
 timeout check from firing and enabling idle or stalled connections to hold daemon slots indefinitely,
 leading to resource exhaustion. (CVE-2026-70462)

Solution

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