Historically, the MD5 checksums in our LFS files serve as a protection
against broken downloads, or accidentally corrupted source files.
While the sources are nowadays downloaded via HTTPS, it make sense to
beef up integrity protection for them, since transparently intercepting
TLS is believed to be feasible for more powerful actors, and the state
of the public PKI ecosystem is clearly not helping.
Therefore, this patch switches from MD5 to BLAKE2, updating all LFS
files as well as make.sh to deal with this checksum algorithm. BLAKE2 is
notably faster (and more secure) than SHA2, so the performance penalty
introduced by this patch is negligible, if noticeable at all.
In preparation of this patch, the toolchain files currently used have
been supplied with BLAKE2 checksums as well on
https://source.ipfire.org/.

This is a bugfix release:
"due to some privacy issues in default settings of Wget, we introduce
this bugfix release.
The --xattr option (saving original URL and Referer into extended file
attributes) was introduced and enabled by default since Wget 1.19.
It possibly saved - possibly unrecognized by the user - credentials,
access tokes etc that were included in the requested URL.
We changed three details as a countermeasure, see below in the NEWS section.
With Best Regards, Tim

NEWS
* Changes in Wget 1.20.1
** --xattr is no longer default since it introduces privacy issues.
** --xattr saves the Referer as scheme/host/port,
user/pw/path/query/fragment
are no longer saved to prevent privacy issues.
** --xattr saves the Original URL without user/password to prevent
privacy issues."

Excerpts from changelog (Details => http://git.savannah.gnu.org/cgit/wget.git):
"Switch off compression by default
Gzip compression has a number of bugs which need to be ironed out before we can support it
by default. Some of these stem from a misunderstanding of the HTTP spec, but a lot of them
are also due to many web servers not
being compliant with RFC 7231.
With this commit, I am marking GZip compression support as experimental
in GNU Wget pending further investigation and the addition of tests.
* src/http.c (gethttp): Fix bug that prevented all files from being decompressed
* src/host.c (sufmatch): Fix to domain matching
Replace HTTP urls with HTTPS where valid
Avoid redirecting output to file when tcgetpgrp fails
* src/log.c (check_redirect_output): tcgetpgrp can return -1 (ENOTTY),
be sure to check whether a valid controlling terminal exists before
redirecting. (Fixes: #51181)
Fix heap overflow in HTTP protocol handling (CVE-2017-13090)
Fix stack overflow in HTTP protocol handling (CVE-2017-13089)"

Fixes CVE-2017-13089
A stack-based buffer overflow when processing chunked, encoded HTTP
responses was found in wget. By tricking an unsuspecting user into
connecting to a malicious HTTP server, an attacker could exploit
this flaw to potentially execute arbitrary code.

Excerpt from annoncement:
"This version fixes a security vulnerability (CVE-2016-4971) present in
all old versions of wget. The vulnerability was discovered by Dawid
Golunski which were reported to us by Beyond Security's SecuriTeam.
On a server redirect from HTTP to a FTP resource, wget would trust the
HTTP server and uses the name in the redirected URL as the destination
filename.
This behaviour was changed and now it works similarly as a redirect from
HTTP to another HTTP resource so the original name is used as
the destination file. To keep the previous behaviour the user must
provide --trust-server-names."
