> Key: HTTPCLIENT-1319
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1319
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Affects Versions: 4.3 Alpha1
> Reporter: Sebb
> Priority: Minor
> Fix For: 4.3 Final
>
>
> The IPV6 compressed format regex allows 0-6 hex groups before and after the ::.
> This does not detect too many groups (there should be at most 7 surrounding groups in total).
> It also allows no groups, i.e "::" which is not permitted AFAIK. [Edit: this is allowed, see http://tools.ietf.org/html/rfc4291#section-2.2]
> The first issue could be detected by counting the number of ':' characters in the string.
> There should be no more than 7 colons.
