Details

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)
