Upgrade Wolfi external-secrets-operator-2.5 to version 2.5.0-r3 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream external-secrets-operator-2.5 package and not the external-secrets-operator-2.5 package as distributed by Wolfi. See How to fix? for Wolfi relevant fixed versions and status.

SSH servers which use CertChecker as a public key callback without setting IsUserAuthority or IsHostAuthority could be caused to panic by a client presenting a certificate. CertChecker now returns an error instead of panicking when these callbacks are nil.
