Design/Logic Flaw

The DHcheckpubkey function in crypto/dh/dhcheck.c in OpenSSL 1.0.2 before 1.0.2f does not ensure that prime numbers are appropriate for Diffie-Hellman DH key exchange, which makes it easier for remote attackers to discover a private DH exponent by making multiple handshakes with a peer that chose...

MGASA-2016-0056 Updated openssl packages fix security vulnerabilities

Updated openssl packages fix security vulnerability: OpenSSL before 1.0.2f would allow for a process to re-use the same private Diffie-Hellman exponent repeatedly during its entire lifetime, which, given that it also allows to use custom DH parameters which may be based on unsafe primes, could...
