+ <ul>
+ <li>Truncated packet could crash via OOB read (CVE-2017-3731)<br/>
+ Severity: Moderate<br/>
+ If an SSL/TLS server or client is running on a 32-bit host, and a specific
+ cipher is being used, then a truncated packet can cause that server or client
+ to perform an out-of-bounds read, usually resulting in a crash.</li>
+ <li>Bad (EC)DHE parameters cause a client crash (CVE-2017-3730)<br/>
+ Severity: Moderate<br/>
+ If a malicious server supplies bad parameters for a DHE or ECDHE key exchange
+ then this can result in the client attempting to dereference a NULL pointer
+ leading to a client crash. This could be exploited in a Denial of Service
+ attack.</li>
+ <li>BN_mod_exp may produce incorrect results on x86_64 (CVE-2017-3732)<br/>
+ Severity: Moderate<br/>
+ There is a carry propagating bug in the x86_64 Montgomery squaring procedure. No
+ EC algorithms are affected. 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 DH 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. An attacker would
+ additionally need online access to an unpatched system using the target
+ private key in a scenario with persistent DH parameters and a private
+ key that is shared between multiple clients. For example this can occur by
+ default in OpenSSL DHE based SSL/TLS ciphersuites. Note: This issue is very
+ similar to CVE-2015-3193 but must be treated as a separate problem.</li>
+ <li>Montgomery multiplication may produce incorrect results (CVE-2016-7055)<br/>
+ Severity: Low<br/>
+ There is a carry propagating bug in the Broadwell-specific Montgomery
+ multiplication procedure that handles input lengths divisible by, but
+ longer than 256 bits. (OpenSSL 1.0.2 only)<br/>
+ This issue was previously fixed in 1.1.0c</li>
