When RSA Fails: Exploiting Prime Selection Vulnerabilities in Public Key Cryptography

This paper explores vulnerabilities in RSA cryptosystems that arise from improper prime number selection during key generation. We examine two primary attack vectors: Fermat's factorization method, which exploits RSA keys generated with primes that are too close together, and the Greatest Common...

DEBIAN-CVE-2016-0701

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...
