Do not allow overwriting unspent transactions (BIP 30)

* a block is not valid if it contains a transaction whose hash

Warning: this is effectively a network rule change, with potential
risk for forking the block chain. Leaving this unfixed carries the
same risk however, for attackers that can cause a reorganisation
in part of the network.

Bugfix and optimize archive_wstring_append_from_mbs()
The cal to mbrtowc() or mbtowc() should read up to mbs_length
bytes and not wcs_length. This avoids out-of-bounds reads.
mbrtowc() and mbtowc() return (size_t)-1 wit errno EILSEQ when
they encounter an invalid multibyte character and (size_t)-2 when
they they encounter an incomplete multibyte character. As we return
failure and all our callers error out it makes no sense to continue
parsing mbs.
As we allocate `len` wchars at the beginning and each wchar has
at least one byte, there will never be need to grow the buffer,
so the code can be left out. On the other hand, we are always
allocatng more memory than we need.
As long as wcs_length == mbs_length == len we can omit wcs_length.
We keep the old code commented if we decide to save memory and
use autoexpanding wcs_length in the future.

virtio-net: fix use after unmap/free for sg
When mergeable buffer is enabled, we try to set the num_buffers after
the virtqueue elem has been unmapped. This will lead several issues,
E.g a use after free when the descriptor has an address which belongs
to the non direct access region. In this case we use bounce buffer
that is allocated during address_space_map() and freed during
address_space_unmap().
Fixing this by storing the elems temporarily in an array and delay the
unmap after we set the the num_buffers.
This addresses CVE-2021-3748.

softmmu: Always initialize xlat in address_space_translate_for_iotlb
The bug is an uninitialized memory read, along the translate_fail
path, which results in garbage being read from iotlb_to_section,
which can lead to a crash in io_readx/io_writex.
The bug may be fixed by writing any value with zero
in ~TARGET_PAGE_MASK, so that the call to iotlb_to_section using
the xlat'ed address returns io_mem_unassigned, as desired by the
translate_fail path.
It is most useful to record the original physical page address,
which will eventually be logged by memory_region_access_valid
when the access is rejected by unassigned_mem_accepts.

virtiofsd: avoid /proc/self/fd tempdir
In order to prevent /proc/self/fd escapes a temporary directory is
created where /proc/self/fd is bind-mounted. This doesn't work on
read-only file systems.
Avoid the temporary directory by bind-mounting /proc/self/fd over /proc.
This does not affect other processes since we remounted / with MS_REC |
MS_SLAVE. /proc must exist and virtiofsd does not use it so it's safe to
do this.
Path traversal can be tested with the following function:
static void test_proc_fd_escape(struct lo_data *lo)
{
int fd;
int level = 0;
ino_t last_ino = 0;
fd = lo->proc_self_fd;
for (;;) {
struct stat st;
if (fstat(fd, &st) != 0) {
perror("fstat");
return;
}
if (last_ino && st.st_ino == last_ino) {
fprintf(stderr, "inode number unchanged, stopping\n");
return;
}
last_ino = st.st_ino;
fprintf(stderr, "Level %d dev %lu ino %lu\n", level,
(unsigned long)st.st_dev,
(unsigned long)last_ino);
fd = openat(fd, "..", O_PATH | O_DIRECTORY | O_NOFOLLOW);
level++;
}
}
Before and after this patch only Level 0 is displayed. Without
/proc/self/fd bind-mount protection it is possible to traverse parent
directories.

Fix illegal client float (CVE-2020-11810)
There is a time frame between allocating peer-id and initializing data
channel key (which is performed on receiving push request or on async
push-reply) in which the existing peer-id float checks do not work right.
If a "rogue" data channel packet arrives during that time frame from
another address and with same peer-id, this would cause client to float
to that new address. This is because:
- tls_pre_decrypt() sets packet length to zero if
data channel key has not been initialized, which leads to
- openvpn_decrypt() returns true if packet length is zero,
which leads to
- process_incoming_link_part1() returns true, which
calls multi_process_float(), which commits float
Note that problem doesn't happen when data channel key is initialized,
since in this case openvpn_decrypt() returns false.
The net effect of this behaviour is that the VPN session for the
"victim client" is broken. Since the "attacker client" does not have
suitable keys, it can not inject or steal VPN traffic from the other
session. The time window is small and it can not be used to attack
a specific client's session, unless some other way is found to make it
disconnect and reconnect first.
CVE-2020-11810 has been assigned to acknowledge this risk.
Fix illegal float by adding buffer length check ("is this packet still
considered valid") before calling multi_process_float().

can cause a double-free along an error path when certain guest files
are empty where we expected those files to contain at least one line.
This causes virt-inspector to crash when run on these guests.
The following is a test case which demonstrates the crash.
`f20rawhidex64' is a Fedora guest, but with small adjustments to the
test you could use any Linux guest for this test.
$ qemu-img create -f qcow2 -b f20rawhidex64 /tmp/test.qcow2
Formatting '/tmp/test.qcow2', fmt=qcow2 size=21474836480 backing_file='f20rawhidex64' encryption=off cluster_size=65536 lazy_refcounts=off
$ guestfish -i -a /tmp/test.qcow2 -- rm /etc/redhat-release : touch /etc/redhat-release
$ virt-inspector /tmp/test.qcow2

better fix could be to check the return value of TIFFFlushData1() in

Reject extraneous data after SSL or GSS encryption handshake.
The server collects up to a bufferload of data whenever it reads data
from the client socket. When SSL or GSS encryption is requested
during startup, any additional data received with the initial
request message remained in the buffer, and would be treated as
already-decrypted data once the encryption handshake completed.
Thus, a man-in-the-middle with the ability to inject data into the
TCP connection could stuff some cleartext data into the start of
a supposedly encryption-protected database session.
This could be abused to send faked SQL commands to the server,
although that would only work if the server did not demand any
authentication data. (However, a server relying on SSL certificate
authentication might well not do so.)
To fix, throw a protocol-violation error if the internal buffer
is not empty after the encryption handshake.
Our thanks to Jacob Champion for reporting this problem.

libpq: reject extraneous data after SSL or GSS encryption handshake.
libpq collects up to a bufferload of data whenever it reads data from
the socket. When SSL or GSS encryption is requested during startup,
any additional data received with the server's yes-or-no reply
remained in the buffer, and would be treated as already-decrypted data
once the encryption handshake completed. Thus, a man-in-the-middle
with the ability to inject data into the TCP connection could stuff
some cleartext data into the start of a supposedly encryption-protected
database session.
This could probably be abused to inject faked responses to the
client's first few queries, although other details of libpq's behavior
make that harder than it sounds. A different line of attack is to
exfiltrate the client's password, or other sensitive data that might
be sent early in the session. That has been shown to be possible with
a server vulnerable to CVE-2021-23214.
To fix, throw a protocol-violation error if the internal buffer
is not empty after the encryption handshake.
Our thanks to Jacob Champion for reporting this problem.

Prevent APC keys with nulls
Summary:
This diff prevents storing APC keys that contain the null byte.
APC uses a backing data structure ConcurrentTableSharedStore that uses const char* as its key type. This leads to situations where inserting APC keys with null bytes will cause key truncation, like so...
localhost> p apc_clear_cache();
true
localhost> p apc_fetch("test")
false
localhost> p apc_fetch("test\x00suffix")
false
localhost> p apc_add("test\x00suffix", 5)
true
localhost> p apc_fetch("test")
5
localhost> p apc_fetch("test\x00suffix")
false
This change will make APC throw an error if a key containing a null byte is passed to the store/add methods.

A chunk of memory allocated by 'req::calloc_noptrs' was being freed by 'free'. The former internally calls 'calloc' and returns a pointer at an index sizeof(MallocNode) inside the allocated buffer. This led to freeing invalid memory.
