Echo: ruby3.3: security update to 3.3.13-0+deb13u1

high Tenable Self-Hosted Container Security Plugin ID 478666

Description

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

- The attack vector is a potential Denial of Service (DoS). The vulnerability is caused by an insufficient
check on the length of a decompressed domain name within a DNS packet. An attacker can craft a malicious
DNS packet containing a highly compressed domain name. When the resolv library parses such a packet, the
name decompression process consumes a large amount of CPU resources, as the library does not limit the
resulting length of the name. This resource consumption can cause the application thread to become
unresponsive, resulting in a Denial of Service condition. (CVE-2025-24294)

Solution

Update the ruby3.3 library and its related packages to version 3.3.13-0+deb13u1 or later.
