—
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.
