The `read_fru_area_section` function only performs size validation of
requested read size, and falsely assumes that the IPMI message will not
respond with more than the requested amount of data; it uses the
unvalidated response size to copy into `frubuf`. If the response is
larger than the request, this can result in overflowing the buffer.
The same issue affects the `read_fru_area` function.'</s> |

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.

[/INST] 'cwe': ['CWE-401'], 'message': 'vnc: fix memory leak when vnc disconnect
Currently when qemu receives a vnc connect, it creates a 'VncState' to
represent this connection. In 'vnc_worker_thread_loop' it creates a
local 'VncState'. The connection 'VcnState' and local 'VncState' exchange
data in 'vnc_async_encoding_start' and 'vnc_async_encoding_end'.
In 'zrle_compress_data' it calls 'deflateInit2' to allocate the libz library
opaque data. The 'VncState' used in 'zrle_compress_data' is the local
'VncState'. In 'vnc_zrle_clear' it calls 'deflateEnd' to free the libz
library opaque data. The 'VncState' used in 'vnc_zrle_clear' is the connection
'VncState'. In currently implementation there will be a memory leak when the
vnc disconnect. Following is the asan output backtrack:

10 0xffffa53965cb in thread_start (/lib64/libc.so.6+0xd55cb)
This is because the opaque allocated in 'deflateInit2' is not freed in
'deflateEnd'. The reason is that the 'deflateEnd' calls 'deflateStateCheck'
and in the latter will check whether 's->strm != strm'(libz's data structure).
This check will be true so in 'deflateEnd' it just return 'Z_STREAM_ERROR' and
not free the data allocated in 'deflateInit2'.
The reason this happens is that the 'VncState' contains the whole 'VncZrle',
so when calling 'deflateInit2', the 's->strm' will be the local address.
So 's->strm != strm' will be true.
To fix this issue, we need to make 'zrle' of 'VncState' to be a pointer.
Then the connection 'VncState' and local 'VncState' exchange mechanism will
work as expection. The 'tight' of 'VncState' has the same issue, let's also turn
it to a pointer.

This is because the opaque allocated in 'deflateInit2' is not freed in
'deflateEnd'. The reason is that the 'deflateEnd' calls 'deflateStateCheck'
and in the latter will check whether 's->strm != strm'(libz's data structure).
This check will be true so in 'deflateEnd' it just return 'Z_STREAM_ERROR' and
not free the data allocated in 'deflateInit2'.
The reason this happens is that the 'VncState' contains the whole 'VncZrle',
so when calling 'deflateInit2', the 's->strm' will be the local address.
So 's->strm != strm' will be true.
To fix this issue, we need to make 'zrle' of 'VncState' to be a pointer.
Then the connection 'VncState' and local 'VncState' exchange mechanism will
work as expection. The 'tight' of 'VncState' has the same issue, let's also turn

This is because the opaque allocated in 'deflateInit2' is not freed in

This check will be true so in 'deflateEnd' it just return 'Z_STREAM_ERROR' and
not free the data allocated in 'deflateInit2'.
The reason this happens is that the 'VncState' contains the whole 'VncZrle',

not free the data allocated in 'deflateInit2'.

So 's->strm != strm' will be true.
To fix this issue, we need to make 'zrle' of 'VncState' to be a pointer.
Then the connection 'VncState' and local 'VncState' exchange mechanism will

This is because the opaque allocated in 'deflateInit2' is not freed in
'deflateEnd'. The reason is that the 'deflateEnd' calls 'deflateStateCheck'
and in the latter will check whether 's->strm != strm'(libz's data structure).
This check will be true so in 'deflateEnd' it just return 'Z_STREAM_ERROR' and
not free the data allocated in 'deflateInit2'.
The reason this happens is that the 'VncState' contains the whole 'VncZrle',
so when calling 'deflateInit2', the 's->strm' will be the local address.
So 's->strm != strm' will be true.
To fix this issue, we need to make 'zrle' of 'VncState' to be a pointer.
Then the connection 'VncState' and local 'VncState' exchange mechanism will
work as expection. The 'tight' of 'VncState' has the same issue, let's also turn
it to a pointer.

[/INST] 'cwe': ['CWE-323'], 'message': 'msg/async/ProtocolV2: avoid AES-GCM nonce reuse vulnerabilities
The secure mode uses AES-128-GCM with 96-bit nonces consisting of a
32-bit counter followed by a 64-bit salt. The counter is incremented
after processing each frame, the salt is fixed for the duration of
the session. Both are initialized from the session key generated
during session negotiation, so the counter starts with essentially
a random value. It is allowed to wrap, and, after 2**32 frames, it
repeats, resulting in nonce reuse (the actual sequence numbers that
the messenger works with are 64-bit, so the session continues on).
Because of how GCM works, this completely breaks both confidentiality
and integrity aspects of the secure mode. A single nonce reuse reveals
the XOR of two plaintexts and almost completely reveals the subkey
used for producing authentication tags. After a few nonces get used
twice, all confidentiality and integrity goes out the window and the
attacker can potentially encrypt-authenticate plaintext of their
choice.
We can't easily change the nonce format to extend the counter to
64 bits (and possibly XOR it with a longer salt). Instead, just
remember the initial nonce and cut the session before it repeats,
forcing renegotiation.

after processing each frame, the salt is fixed for the duration of
the session. Both are initialized from the session key generated
during session negotiation, so the counter starts with essentially
a random value. It is allowed to wrap, and, after 2**32 frames, it
repeats, resulting in nonce reuse (the actual sequence numbers that
the messenger works with are 64-bit, so the session continues on).
Because of how GCM works, this completely breaks both confidentiality
and integrity aspects of the secure mode. A single nonce reuse reveals
the XOR of two plaintexts and almost completely reveals the subkey
used for producing authentication tags. After a few nonces get used
twice, all confidentiality and integrity goes out the window and the
attacker can potentially encrypt-authenticate plaintext of their
choice.
We can't easily change the nonce format to extend the counter to
64 bits (and possibly XOR it with a longer salt). Instead, just
remember the initial nonce and cut the session before it repeats,
forcing renegotiation.

[/INST] 'cwe': ['CWE-323'], 'message': 'msg/async/crypto_onwire: fix endianness of nonce_t
As a AES-GCM IV, nonce_t is implicitly shared between server and
client. Currently, if their endianness doesn't match, they are unable
to communicate in secure mode because each gets its own idea of what
the next nonce should be after the counter is incremented.
Several RFCs state that the nonce counter should be BE, but since we
use LE for everything on-disk and on-wire, make it LE.
