+ <h1>Problem Description:</h1>
+ <p>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.</p>
+ <p>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]</p>
+ <p>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.</p>
+ <h1>Impact:</h1>
+ <p>Applications with incorrect error handling may inappropriately
+ pass unencrypted data. [CVE-2017-3737]</p>
+ <p>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.</p>
+ <p>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]</p>
