Advisory ID: SLSA-2014:0625-1
Issue Date: 2014-06-05
CVE Numbers: CVE-2010-5298
CVE-2014-0198
CVE-2014-0224
CVE-2014-0221
CVE-2014-0195
CVE-2014-3470
—
It was found that OpenSSL clients and servers could be forced, via a
specially crafted handshake packet, to use weak keying material for
communication. A man-in-the-middle attacker could use this flaw to decrypt
and modify traffic between a client and a server. (CVE-2014-0224)
Note: In order to exploit this flaw, both the server and the client must
be using a vulnerable version of OpenSSL; the server must be using OpenSSL
version 1.0.1 and above, and the client must be using any version of
OpenSSL. For more information about this flaw, refer to:
A buffer overflow flaw was found in the way OpenSSL handled invalid DTLS
packet fragments. A remote attacker could possibly use this flaw to
execute arbitrary code on a DTLS client or server. (CVE-2014-0195)
Multiple flaws were found in the way OpenSSL handled read and write
buffers when the SSL_MODE_RELEASE_BUFFERS mode was enabled. A TLS/SSL
client or server using OpenSSL could crash or unexpectedly drop
connections when processing certain SSL traffic. (CVE-2010-5298,
CVE-2014-0198)
A denial of service flaw was found in the way OpenSSL handled certain DTLS
ServerHello requests. A specially crafted DTLS handshake packet could
cause a DTLS client using OpenSSL to crash. (CVE-2014-0221)
A NULL pointer dereference flaw was found in the way OpenSSL performed
anonymous Elliptic Curve Diffie Hellman (ECDH) key exchange. A specially
crafted handshake packet could cause a TLS/SSL client that has the
anonymous ECDH cipher suite enabled to crash. (CVE-2014-3470)
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.
