Summary
There are multiple vulnerabilities in OpenSSL that is used by PowerKVM. 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.
CVSS Base Score: 5
CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/95166 for more
information
