A number of security flaws in golang-yaml.v2 were tackled in Ubuntu Security Notice USN-6287-1, released on August 14, 2023.
Several security issues were patched in the Go yaml package.

Summary

Several security issues were patched in the Go yaml package.

Software Description:

- golang-yaml.v2: YAML support for the Go language

Details:

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)
