The capability check in nfnetlink_rcv() verifies that the caller
has CAP_NET_ADMIN in the namespace that "owns" the netlink socket.
However, nfnl_cthelper_list is shared by all net namespaces on the
system.  An unprivileged user can create user and net namespaces
in which he holds CAP_NET_ADMIN to bypass the netlink_net_capable()
check:

    $ nfct helper list

Add capable() checks in nfnetlink_cthelper, as this is cleaner than
trying to generalize the solution.

 'cwe': ['CWE-787'], 'message': 'Bug 739133 - (CVE-2017-17785) Heap overflow while parsing FLI files.

It is possible to trigger a heap overflow while parsing FLI files. The
RLE decoder is vulnerable to out of boundary writes due to lack of
boundary checks.

The variable "framebuf" points to a memory area which was allocated
with fli_header->width * fli_header->height bytes. The RLE decoder
therefore must never write beyond that limit.

If an illegal frame is detected, the parser won't stop, which means
that the next valid sequence is properly parsed again. This should
allow GIMP to parse FLI files as good as possible even if they are
broken by an attacker or by accident.

While at it, I changed the variable xc to be of type size_t, because
the multiplication of width and height could overflow a 16 bit type.

 'cwe': ['CWE-125'], 'message': 'cirrus: handle negative pitch in cirrus_invalidate_region()

cirrus_invalidate_region() calls memory_region_set_dirty()
on a per-line basis, always ranging from off_begin to
off_begin+bytesperline. With a negative pitch off_begin
marks the top most used address and thus we need to do an
initial shift backwards by a line for negative pitches of
backward blits, otherwise the first iteration covers the
line going from the start offset forwards instead of
backwards.
Additionally since the start address is inclusive, if we
shift by a full `bytesperline` we move to the first address
*not* included in the blit, so we only shift by one less
than bytesperline.

 'cwe': ['CWE-362'], 'message': 'ALSA: seq: Make ioctls race-free

The ALSA sequencer ioctls have no protection against racy calls while
the concurrent operations may lead to interfere with each other.  As
reported recently, for example, the concurrent calls of setting client
pool with a combination of write calls may lead to either the
unkillable dead-lock or UAF.

As a slightly big hammer solution, this patch introduces the mutex to
make each ioctl exclusive.  Although this may reduce performance via
parallel ioctl calls, usually it's not demanded for sequencer usages,
hence it should be negligible.

If you take a GSO skb, and split it into packets, will the MAC
length (L2 + L3 + L4 headers + payload) of those packets be small
enough to fit within a given length?

Move skb_gso_mac_seglen() to skbuff.h with other related functions
like skb_gso_network_seglen() so we can use it, and then create
skb_gso_validate_mac_len to do the full calculation.
