"A race condition was found in the way OpenSSL handled ServerHello
messages with an included Supported EC Point Format extension. A
malicious server could possibly use this flaw to cause a
multi-threaded TLS/SSL client using OpenSSL to write into freed
memory, causing the client to crash or execute arbitrary code.
(CVE-2014-3509)

It was discovered that the OBJ_obj2txt() function could fail to
properly NUL-terminate its output. This could possibly cause an
application using OpenSSL functions to format fields of X.509
certificates to disclose portions of its memory. (CVE-2014-3508)

A flaw was found in the way OpenSSL handled fragmented handshake
packets. A man-in-the-middle attacker could use this flaw to force a
TLS/SSL server using OpenSSL to use TLS 1.0, even if both the client
and the server supported newer protocol versions. (CVE-2014-3511)

Multiple flaws were discovered in the way OpenSSL handled DTLS
packets. A remote attacker could use these flaws to cause a DTLS
server or client using OpenSSL to crash or use excessive amounts of
memory. (CVE-2014-3505, CVE-2014-3506, CVE-2014-3507)

A NULL pointer dereference flaw was found in the way OpenSSL performed
a handshake when using the anonymous Diffie-Hellman (DH) key exchange.
A malicious server could cause a DTLS client using OpenSSL to crash if
that client had anonymous DH cipher suites enabled. (CVE-2014-3510)

For the update to take effect, all services linked to the OpenSSL
library (such as httpd and other SSL-enabled services) must be
restarted or the system rebooted."
