CVSS 8.100000381469727 HIGH
A flaw was found in the `encoding/asn1` package in Go. An attacker could provide a specially crafted, deeply-nested Abstract Syntax Notation One (ASN.1) structure, leading to excessive recursion during the `Unmarshal` operation. This could result in stack exhaustion and a Denial of Service (DoS) condition.
