high Nessus Plugin ID 172441

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 host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5944-1 advisory.

It was discovered that SnakeYAML did not limit the maximal nested depth for collections when parsing YAML data. If a user or automated system were tricked into opening a specially crafted YAML file, an attacker could possibly use this issue to cause applications using SnakeYAML to crash, resulting in a denial of service. (CVE-2022-25857, CVE-2022-38749, CVE-2022-38750)

It was discovered that SnakeYAML did not limit the maximal data matched with regular expressions when parsing YAML data. If a user or automated system were tricked into opening a specially crafted YAML file, an attacker could possibly use this issue to cause applications using SnakeYAML to crash, resulting in a denial of service. (CVE-2022-38751)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected libyaml-snake-java package.
