Vulnerability Details

CVE-ID: CVE-2014-3567

DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a memory leak when handling failed session ticket integrity checks. By sending an overly large number of invalid session tickets, an attacker could exploit this vulnerability to exhaust all available memory of an SSL/TLS or DTLS server.

CVSS Base Score: 5.0
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/97036 for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P)

CVE-ID: CVE-2014-3568

DESCRIPTION: OpenSSL could allow a remote attacker bypass security restrictions. When configured with “no-ssl3” as a build option, servers could accept and complete a SSL 3.0 handshake. An attacker could exploit this vulnerability to perform unauthorized actions.

CVSS Base Score: 2.6
CVSS Temporal Score: See https://exchange.xforce.ibmcloud.com/vulnerabilities/97037 for more information
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:H/Au:N/C:N/I:P/A:N)

CVE-ID: CVE-2014-3511

DESCRIPTION: OpenSSL could allow a remote attacker to bypass security restrictions, caused by the negotiation of TLS 1.0 instead of higher protocol versions by the OpenSSL SSL/TLS server code when handling a badly fragmented ClientHello message. An attacker could exploit this vulnerability using man-in-the-middle techniques to force a downgrade to TLS 1.0.

CVSS Base Score: 4.3
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/95162&gt; for more information
CVSS Environmental Score:*: Undefined
CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N)

CVE-ID: CVE-2014-3508

DESCRIPTION: OpenSSL could allow a remote attacker to obtain sensitive information, caused by an error in OBJ_obj2txt. If applications echo pretty printing output, an attacker could exploit this vulnerability to read information from the stack.

CVSS Base Score: 4.3
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/95165&gt; for more information
