This will cause the client to spend an unreasonably long period of time generating a key for this prime resulting in a hang until the client has finished. This could be exploited in a Denial Of Service attack. This issue was reported to OpenSSL on 5th June 2018 by Guido Vranken (CVE-2018-0732) [Guido Vranken] *) Cache timing vulnerability in RSA Key Generation The OpenSSL RSA Key generation algorithm has been shown to be vulnerable to a cache timing side channel attack. An attacker with sufficient access to mount cache timing attacks during the RSA key generation process could recover the private key. This issue was reported to OpenSSL on 4th April 2018 by Alejandro Cabrera Aldaya, Billy Brumley, Cesar Pereida Garcia and Luis Manuel Alvarez Tapia. (CVE-2018-0737) [Billy Brumley] *) Make EVP_PKEY_asn1_new() a bit stricter about its input. A NULL pem_str parameter is no longer accepted, as it leads to a corrupt table. NULL pem_str is reserved for alias entries only.
