Hi,

both errors have in common that there are about an change of allowed 
hostnames.
But as for the second bug there is an big mistake. The underscore is 
allowed for SRV and CNAME
but not for A records. For SRV records it is wide used in LDAP records 
for MS Domain System (PDC).
But the Subject Alias is about valid hostnames so only the Number as you 
mentioned should be allowed
as first character.
