Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 16.04 ESM / 18.04 LTS / 20.04 LTS / 22.04 LTS / 22.10 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5944-1 advisory.

 - The package org.yaml:snakeyaml from 0 and before 1.31 are vulnerable to Denial of Service (DoS) due missing to nested depth limitation for collections. (CVE-2022-25857)
