It was discovered that OpenSSL did not correctly perform Montgomery multiplications. Local attackers might be able to reconstruct RSA private keys by examining another user’s OpenSSL processes. (CVE-2007-3108)
Moritz Jodeit discovered that OpenSSL’s SSL_get_shared_ciphers function did not correctly check the size of the buffer it was writing to. A remote attacker could exploit this to write one NULL byte past the end of an application’s cipher list buffer, possibly leading to arbitrary code execution or a denial of service. (CVE-2007-5135)
