high Nessus Plugin ID 179734

Language:

Synopsis

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

Description

The remote Ubuntu 16.04 ESM host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-6287-1 advisory.

 - Due to unbounded alias chasing, a maliciously crafted YAML file can cause the system to consume significant system resources. If parsing user input, this may be used as a denial of service vector.
 (CVE-2021-4235)

 - Parsing malicious or large YAML documents can consume excessive amounts of CPU or memory. (CVE-2022-3064)

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 golang-gopkg-yaml.v2-dev and / or golang-yaml.v2-dev packages.
