[Security] Bump js-yaml from 3.12.0 to 3.14.0

[dependabot-preview]

Bumps js-yaml from 3.12.0 to 3.14.0. This update includes security fixes.

Vulnerabilities fixed

Sourced from The GitHub Security Advisory Database.

Denial of Service in js-yaml Versions of js-yaml prior to 3.13.0 are vulnerable to Denial of Service. By parsing a carefully-crafted YAML file, the node process stalls and may exhaust system resources leading to a Denial of Service.

Recommendation

Upgrade to version 3.13.0.

Affected versions: < 3.13.0

Sourced from The GitHub Security Advisory Database.

Code Injection in js-yaml Versions of js-yaml prior to 3.13.1 are vulnerable to Code Injection. The load() function may execute arbitrary code injected through a malicious YAML file. Objects that have toString as key, JavaScript code as value and are used as explicit mapping keys allow attackers to execute the supplied code through the load() function. The safeLoad() function is unaffected.

An example payload is { toString: ! 'function (){return Date.now()}' } : 1 which returns the object { "1553107949161": 1 }

Recommendation

Upgrade to version 3.13.1.

Affected versions: < 3.13.1
