"Invoking SSL_read()/SSL_write() while in an error state causes data to
be passed without being decrypted/encrypted directly from the SSL/TLS
record layer.

In order to exploit this issue an application bug would have to be
present that resulted in a call to SSL_read()/SSL_write() being issued
after having already received a fatal error. [CVE-2017-3737]

There is an overflow bug in the x86_64 Montgomery multiplication
procedure used in exponentiation with 1024-bit moduli. This only
affects processors that support the AVX2 but not ADX extensions like
Intel Haswell (4th generation). [CVE-2017-3738] This bug only affects
FreeBSD 11.x. Impact : Applications with incorrect error handling may
inappropriately pass unencrypted data. [CVE-2017-3737]

Mishandling of carry propagation will produce incorrect output, and
make it easier for a remote attacker to obtain sensitive private-key
information. No EC algorithms are affected and analysis suggests that
attacks against RSA and DSA as a result of this defect would be very
difficult to perform and are not believed likely.

Attacks against DH1024 are considered just feasible (although very
difficult) because most of the work necessary to deduce information
about a private key may be performed offline. The amount of resources
required for such an attack would be very significant and likely only
accessible to a limited number of attackers. However, for an attack on
TLS to be meaningful, the server would have to share the DH1024
private key among multiple clients, which is no longer an option since
CVE-2016-0701. [CVE-2017-3738]"
