CVE-2017-1000367 - Potential overwrite of arbitrary files on Linux
On Linux systems, sudo parses the /proc/[pid]/stat file to determine the
device number of the process's tty (field 7). The fields in the file are
space-delimited, but it is possible for the command name (field 2) to
include spaces, which sudo does not account for. A user with sudo
privileges can cause sudo to use a device number of the user's choosing by
creating a symbolic link from the sudo binary to a name that contains a
space, followed by a number.
If SELinux is enabled on the system and sudo was built with SELinux support,
a user with sudo privileges may be able to to overwrite an arbitrary file.
This can be escalated to full root access by rewriting a trusted file such
as /etc/shadow or even /etc/sudoers.

CVE-2017-9022 - RSA public keys passed to the gmp plugin aren't
validated sufficiently before attempting signature verification, so that
invalid input might lead to a floating point exception and crash of the
process. A certificate with an appropriately prepared public key sent by a
peer could be used for a denial-of-service attack.

CVE-2017-9023 - ASN.1 CHOICE types are not correctly handled by the ASN.1
parser when parsing X.509 certificates with extensions that use such types.
This could lead to infinite looping of the thread parsing a specifically

maekdev() is available from sys/types.h but only due to a bug in glibc. This
is being fixed by printing an error when using makedev() from sys/types.h.
To fix the issue we should include sys/sysmacros.h for makedev(). As this
has already been fixed in upstream Xen we can backport the patch.

madplay use a libtool script in version 1.5.2 but the libtool patch
"buildroot-libtool-v1.5.patch.patch" doesn't apply.
From [1]:
"It's libtool dropping -static. That's because madplay has a
weird version of libtool, on which our libtool patch doesn't apply so
we have MADPLAY_LIBTOOL_PATCH = NO. Therefore, the hack we have that
makes libtool -static behave like -all-static isn't applied, causing
this build failure."

The external toolchain code has some logic to calculate the correct name
for the dynamic linker symbolic link that needs to be created when the
musl C library is being used. There was already some handling for the
mipsel+soft-float case, but not for the mips+soft-float case. Due to
this, the symbolic link was incorrectly named, and programs were
referencing an non-existing file.

The Docker engine can optionally log to systemd-journald. For this

m68k coldfire causes ffmpeg to think atomic intrinsics are available,
so ffmpeg doesn't use its fallback on pthreads based atomic
operations. However, m68k coldfire doesn't provide properly working
sync 4 atomics, causing a build failure.
Since fixing ffmpeg on m68k coldfire is not really important (who
wants to use ffmpeg on such platform?), we simply disallow the
selection of ffmpeg on this platform.
Alternate approaches have been proposed in the past:
- Bernd Kuhls proposed in http://patchwork.ozlabs.org/patch/766909/
to add a dependency on BR2_TOOLCHAIN_HAS_SYNC_4, but this is wrong
because other architectures that lack sync 4 atomics, such as
Sparc, can build ffmpeg perfectly fine thanks to the pthreads based
fallback code.
- Waldemar Brodkorb proposed in
https://patchwork.ozlabs.org/patch/756664/ to add an explicit
option in ffmpeg configure to force the use of pthreads based
atomics. However, we believe that running ffmpeg on m68k coldfire
is such an unlikely use case that it isn't worth carrying a patch
for this.

The gnutils code uses __attribute__((constructor)) and
__attribute__((destructor)) to call constructor/desctructor when a
shared library is loaded.
Constructor/desctructor are not used when a static library is used
(except when if -Wl,--whole-archive -lgnutls -Wno-whole-archive is
used, not tested).
Even if gnutls initialization (_gnutls_global_init()) may be
called manually, the gnutls maintainer said it's not supported [1].
"Note that static linking applications with gnutls is not something
supported. gnutls relies on library constructors and destructors
which are not loaded when linking statically."
Now the gnutls script warns about static linking [2].
So disable gnutls statically by adding "depends on !BR2_STATIC_LIBS"
at Kconfig level and --disable-static in GNUTLS_CONF_OPTS.

As reported by Bernd [1], using POST_EXTRACT to copy
linux_syscall_support.h break the legal-info target when
google-breakpad package is selected:
/usr/bin/install: cannot stat '/home/bernd/buildroot/buildroot/output/ost/usr/i586-buildroot-linux-uclibc/sysroot/usr/include/linux_syscall_support.h': No such file or directory
This is because linux_syscall_support.h is installed by a dependency
of google-breakpad, and dependencies are only guaranteed to be
available for the configure step of a package. To fix this, we use a
PRE_CONFIGURE hook instead of POST_EXTRACT hook.

Prior to glibc 2.18, definitions like SIZE_MAX or INT_FAST32_MAX from
<stdint.h> were only made available for C code, or in C++ if
__STDC_LIMIT_MACROS was defined.
The code from jasper uses such definitions, without defining
__STDC_LIMIT_MACROS. Unfortunately, defining __STDC_LIMIT_MACROS in
the jasper headers doesn't work, since <stdint.h> has already been
included before, at a point where __STDC_LIMIT_MACROS was not defined.
So to solve this problem, we simply pass -D__STDC_LIMIT_MACROS in
CXXFLAGS when building opencv with jasper support.
This patch uses the same solution used for libraw:
