Subject: [PATCH] [release-branch.go1.21] net/http, net/http/cookiejar: avoid
subdomain matches on IPv6 zones
When deciding whether to forward cookies or sensitive headers
across a redirect, do not attempt to interpret an IPv6 address
as a domain name.
Avoids a case where a maliciously-crafted redirect to an
IPv6 address with a scoped addressing zone could be
misinterpreted as a within-domain redirect. For example,
we could interpret "::1%.www.example.com" as a subdomain
of "www.example.com".
Thanks to Juho Nurminen of Mattermost for reporting this issue.

Subject: [PATCH] [release-branch.go1.21] net/textproto, mime/multipart: avoid
unbounded read in MIME header
mime/multipart.Reader.ReadForm allows specifying the maximum amount
of memory that will be consumed by the form. While this limit is
correctly applied to the parsed form data structure, it was not
being applied to individual header lines in a form.
For example, when presented with a form containing a header line
that never ends, ReadForm will continue to read the line until it
runs out of memory.
Limit the amount of data consumed when reading a header.
