8 years agoEnsure that libcrypto and libssl do not unload until the process exits
Matt Caswell [Tue, 18 Oct 2016 13:13:25 +0000 (14:13 +0100)]
Ensure that libcrypto and libssl do not unload until the process exits

Because we use atexit() to cleanup after ourselves, this will cause a
problem if we have been dynamically loaded and then unloaded again: the
atexit() handler may no longer be there.

Most modern atexit() implementations can handle this, however there are
still difficulties if libssl gets unloaded before libcrypto, because of
the atexit() callback that libcrypto makes to libssl.

The most robust solution seems to be to ensure that libcrypto and libssl
never unload. This is done by simply deliberately leaking a dlopen()
reference to them.

8 years agoFix read_ahead
Matt Caswell [Wed, 2 Nov 2016 10:34:12 +0000 (10:34 +0000)]
Fix read_ahead

The function ssl3_read_n() takes a parameter |clearold| which, if set,
causes any old data in the read buffer to be forgotten, and any unread data
to be moved to the start of the buffer. This is supposed to happen when we
first read the record header.

However, the data move was only taking place if there was not already
sufficient data in the buffer to satisfy the request. If read_ahead is set
then the record header could be in the buffer already from when we read the
preceding record. So with read_ahead we can get into a situation where even
though |clearold| is set, the data does not get moved to the start of the
read buffer when we read the record header. This means there is insufficient
room in the read buffer to consume the rest of the record body, resulting in
an internal error.

This commit moves the |clearold| processing to earlier in ssl3_read_n()
to ensure that it always takes place.

Fix a mem leak in NPN handling

If a server sent multiple NPN extensions in a single ClientHello then a
mem leak can occur. This will only happen where the client has requested
NPN in the first place. It does not occur during renegotiation. Therefore
the maximum that could be leaked in a single connection with a malicious
server is 64k (the maximum size of the ServerHello extensions section). As
this is client side, only occurs if NPN has been requested and does not
occur during renegotiation this is unlikely to be exploitable.

Excessive allocation of memory in dtls1_preprocess_fragment()

This issue is very similar to CVE-2016-6307 described in the previous
commit. The underlying defect is different but the security analysis and
impacts are the same except that it impacts DTLS.

A DTLS message includes 3 bytes for its length in the header for the
message.
This would allow for messages up to 16Mb in length. Messages of this length
are excessive and OpenSSL includes a check to ensure that a peer is sending
reasonably sized messages in order to avoid too much memory being consumed
to service a connection. A flaw in the logic of version 1.1.0 means that
memory for the message is allocated too early, prior to the excessive
message length check. Due to way memory is allocated in OpenSSL this could
mean an attacker could force up to 21Mb to be allocated to service a
connection. This could lead to a Denial of Service through memory
exhaustion. However, the excessive message length check still takes place,
and this would cause the connection to immediately fail. Assuming that the
application calls SSL_free() on the failed conneciton in a timely manner
then the 21Mb of allocated memory will then be immediately freed again.
Therefore the excessive memory allocation will be transitory in nature.
This then means that there is only a security impact if:

1) The application does not call SSL_free() in a timely manner in the
event that the connection fails
or
2) The application is working in a constrained environment where there
is very little free memory
or
3) The attacker initiates multiple connection attempts such that there
are multiple connections in a state where memory has been allocated for
the connection; SSL_free() has not yet been called; and there is
insufficient memory to service the multiple requests.

Except in the instance of (1) above any Denial Of Service is likely to
be transitory because as soon as the connection fails the memory is
subsequently freed again in the SSL_free() call. However there is an
increased risk during this period of application crashes due to the lack
of memory - which would then mean a more serious Denial of Service.

This issue does not affect TLS users.
