These issues were disclosed on August 6, 2014 by the OpenSSL Project. OpenSSL is used in PowerKVM to secure communications with the Kimchi management agent and the libvirtd virtualization management daemon. Vulnerability Details - ------------------------------------------------------------------------------ CVE-ID: CVE-2014-3512 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by an internal buffer overrun. A remote attacker could exploit this vulnerability using invalid SRP parameters sent from a malicious server or client to cause a denial of service. CVSS Base Score: 5 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/95158 for more information CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P) - ------------------------------------------------------------------------------- CVE-ID: CVE-2014-3509 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a race condition in the ssl_parse_serverhello_tlsext() code. If a multithreaded client connects to a malicious server using a resumed session, a remote attacker could exploit this vulnerability to cause a denial of service. CVSS Base Score: 4.3 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/95159 for more information CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:N/A:P) - ------------------------------------------------------------------------------- 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. CVSS Base Score: 5 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/95160 for more information CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P) - ------------------------------------------------------------------------------- CVE-ID: CVE-2014-3507 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. CVSS Base Score: 5 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/95161 for more information CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P) - ------------------------------------------------------------------------------- CVE-ID: CVE-2014-3511 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 http://xforce.iss.net/xforce/xfdb/95162 for more information CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N) - ------------------------------------------------------------------------------- CVE-ID: CVE-2014-3505 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. CVSS Base Score: 5 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/95163 for more information CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:L/Au:N/C:N/I:N/A:P) - ------------------------------------------------------------------------------- CVE-ID: CVE-2014-3510 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. CVSS Base Score: 4.3 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/95164 for more information CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:N/A:P) - ------------------------------------------------------------------------------- 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 http://xforce.iss.net/xforce/xfdb/95165 for more information CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:M/Au:N/C:P/I:N/A:N) - ------------------------------------------------------------------------------- CVE-ID: CVE-2014-5139 DESCRIPTION: OpenSSL is vulnerable to a denial of service, caused by a NULL pointer dereference when an SRP ciphersuite is specified without being properly negotiated with the client. A remote attacker could exploit this vulnerability to cause the client to crash.
