Ubuntu 16.04 ESM / 18.04 ESM / 20.04 LTS : Go yaml vulnerabilities (USN-6287-1)

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 / 18.04 ESM / 20.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-6287-1 advisory.

 Simon Ferquel discovered that the Go yaml package incorrectly handled certain YAML documents. If a user or an automated system were tricked into opening a specially crafted input file, a remote attacker could possibly use this issue to cause the system to crash, resulting in a denial of service. (CVE-2021-4235)

 It was discovered that the Go yaml package incorrectly handled certain large YAML documents. If a user or an automated system were tricked into opening a specially crafted input file, a remote attacker could possibly use this issue to cause the system to crash, resulting in a denial of service. (CVE-2022-3064)

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