Several security issues were fixed in OpenSSL ...
It was discovered that OpenSSL did not always use constant time operations when computing Digital Signature Algorithm (DSA) signatures A local attacker could possibly use this flaw to obtain a private DSA key belonging to another user or service running on the same system (CVE-2016-2178) It was discovered that the Datagram TLS (DTLS) implementati ...
An out of bounds write flaw was discovered in the OpenSSL BN_bn2dec() function An attacker able to make an application using OpenSSL to process a large BIGNUM could cause the application to crash or, possibly, execute arbitrary code ...
The function BN_bn2dec() does not check the return value of BN_div_word() This can cause an OOB write if an application uses this function with an overly large BIGNUM This could be a problem if an overly large certificate or CRL is printed out from an untrusted source TLS is not affected because record limits will reject an oversized certificate ...
