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).
Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
