CVE-ID: CVE-2015-0293

Description: OpenSSL is vulnerable to a denial of service. By sending a specially-crafted SSLv2 CLIENT-MASTER-KEY message, a remote attacker could exploit this vulnerability to trigger an assertion.

CVSS Base Score: 5
CVSS Temporal Score: See <http://exchange.xforce.ibmcloud.com/vulnerabilities/101671&gt; for current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVE-ID: CVE-2015-1787

Description: OpenSSL is vulnerable to a denial of service, caused by an error when client auth is used. By sending an empty ClientKeyExchange message, a remote attacker could exploit this vulnerability to trigger a segmentation fault.
