The {TempoShortName} 3.8.2 patch release includes a fix for the following issue:
CVE-2025-61729::
Before this update, the `HostnameError.Error()` function in the Go `crypto/x509` package used string concatenation in a loop without limiting the number of printed hostnames. This behavior caused quadratic runtime when processing certificates with many hostnames, allowing attackers to consume excessive resources. With this update, the function uses the Go `strings.Builder` programming element for efficient string construction and limits the number of hostnames in an error message to 99. As a result, the function now runs efficiently even for certificates with many hostnames.
