Security Bulletin: Network Protection is affected by multiple OpenSSL vulnerabilities (CVE-2014-3505, CVE-2014-3506, CVE-2014-3507, CVE-2014-3510, CVE-2014-3511)

Vulnerability Details

CVE-ID: CVE-2014-3505

Description: OpenSSL is vulnerable to a denial of service, caused by a double-free error when handling DTLS packets. A remote attacker could exploit this vulnerability to cause the system to crash.

The attack does not require local network access, authentication, or specialized knowledge and techniques. An exploit would not affect the integrity of data or confidentiality of information, but it could impact the availability of the system

CVE-ID: CVE-2014-3506

Description: OpenSSL is vulnerable to a denial of service, caused by an error when processing DTLS handshake messages. A remote attacker could exploit this vulnerability to consume an overly large amount of memory.

The attack does not require local network access, authentication, or specialized knowledge and techniques. An exploit would not affect the integrity of data or confidentiality of information, but it could impact the availability of the system.

CVE-ID: CVE-2014-3507

Description: OpenSSL is vulnerable to a denial of service. By sending specially-crafted DTLS packets, a remote attacker could exploit this vulnerability to leak memory and cause a denial of service.

The attack does not require local network access, authentication, or specialized knowledge and techniques. An exploit would not affect the integrity of data or confidentiality of information, but it could impact the availability of the system.

CVE-ID: CVE-2014-3510

Description: OpenSSL is vulnerable to a denial of service, caused by a NULL pointer dereference in anonymous ECDH ciphersuites. A remote attacker could exploit this vulnerability using a malicious handshake to cause the client to crash.

The attack does not require local network access or authentication, but some specialized knowledge and techniques are required. An exploit would not affect the integrity of data or confidentiality of information, but it could impact the availability of the system.

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.

The attack does not require local network access or authentication, but some specialized knowledge and techniques are required. An exploit would not affect the availability of the system or confidentiality of information, but it could impact the integrity of data.
