Fixes:
GNUTLS-SA-2017-3A - Addressed integer overflow resulting to invalid
memory write in OpenPGP certificate parsing.
GNUTLS-SA-2017-3B - Addressed crashes in OpenPGP certificate parsing,
related to private key parser. No longer allow OpenPGP certificates
(public keys) to contain private key sub-packets.
GNUTLS-SA-2017-3C - Addressed large allocation in OpenPGP certificate
parsing, that could lead in out-of-memory condition.

Fixes CVE-2017-2629 - curl SSL_VERIFYSTATUS ignored
>From the advisory (http://www.openwall.com/lists/oss-security/2017/02/21/6):
Curl and libcurl support "OCSP stapling", also known as the TLS Certificate
Status Request extension (using the `CURLOPT_SSL_VERIFYSTATUS` option). When
telling curl to use this feature, it uses that TLS extension to ask for a
fresh proof of the server's certificate's validity. If the server doesn't
support the extension, or fails to provide said proof, curl is expected to
return an error.
Due to a coding mistake, the code that checks for a test success or failure,
ends up always thinking there's valid proof, even when there is none or if the
server doesn't support the TLS extension in question. Contrary to how it used
to function and contrary to how this feature is documented to work.
This could lead to users not detecting when a server's certificate goes
invalid or otherwise be mislead that the server is in a better shape than it
is in reality.

The latest dbus release 1.10.16 fixes two symlink attacks in
non-production-suitable configurations. I am treating these as bugs
rather than practical vulnerabilities, and very much hope neither of
these is going to affect any real users, but I'm reporting them to
oss-security in case there's an attack vector that I've missed.
No CVEs assigned so far.

Jann Horn, Project Zero (Google) discovered that ntfs-3g, a read-write
NTFS driver for FUSE does not not scrub the environment before
executing modprobe to load the fuse module. This influence the behavior
of modprobe (MODPROBE_OPTIONS environment variable, --config and
--dirname options) potentially allowing for local root privilege
escalation if ntfs-3g is installed setuid.
Notice that Buildroot does NOT install netfs-3g setuid root, but custom
permission tables might be used, causing it to vulnerable to the above.
ntfs-3g does not seem to have a publicly available version control system
and no new releases have been made, so instead grab the patch from Debian.

On Darwin, user's trust preferences for root certificates were not honored.
If the user had a root certificate loaded in their Keychain that was
explicitly not trusted, a Go program would still verify a connection using
that root certificate. This is addressed by https://golang.org/cl/33721,
tracked in https://golang.org/issue/18141. Thanks to Xy Ziemba for
identifying and reporting this issue.
The net/http package's Request.ParseMultipartForm method starts writing to
temporary files once the request body size surpasses the given "maxMemory"
limit. It was possible for an attacker to generate a multipart request
crafted such that the server ran out of file descriptors. This is addressed
by https://golang.org/cl/30410, tracked in https://golang.org/issue/17965.

Fixes#9576
When the path to a br2-external tree is relative, make enters an endless
recursive loop (paths elided for brevity):
$ make BR2_EXTERNAL=.. foo_defconfig
make[1]: stat: ../configs/../configs/../configs[...]/toto_defconfig: Filename too long
make[1]: *** No rule to make target '../configs/../configs/../configs[...]/toto_defconfig',
needed by '../configs/../configs/../configs[...]/toto_defconfig'. Stop.
Makefile:79: recipe for target '_all' failed
make: *** [_all] Error 2
It is a bit complex to understand the actual technical reason for this
never-ending expansion; it seems it happens in the code generated by the
percent_defconfig macro. Not sure why, though...
But the root cause is the relative path.
Just use absolute, canonical paths to br2-external trees. Always.
