CVSS 7.5 HIGH
A flaw was found in golang. A remote attacker could exploit this vulnerability by providing a specially crafted certificate during the error string construction process within the `HostnameError.Error()` function. This flaw, caused by unbounded string concatenation, leads to excessive resource consumption. Successful exploitation can result in a denial of service (DoS) for the affected system.
