This script is Copyright (C) 2015-2016 Tenable Network Security, Inc.


Synopsis :

The remote SUSE host is missing one or more security updates.

Description :

OpenSSL 0.9.8j was updated to fix several security issues.

CVE-2015-4000: The Logjam Attack ( weakdh.org ) has been addressed by
rejecting connections with DH parameters shorter than 1024 bits. We
now also generate 2048-bit DH parameters by default.

CVE-2015-1788: Malformed ECParameters could cause an infinite loop.

CVE-2015-1789: An out-of-bounds read in X509_cmp_time was fixed.

CVE-2015-1790: A PKCS7 decoder crash with missing EnvelopedContent was
fixed.

CVE-2015-1792: A CMS verification infinite loop when using an unknown
hash function was fixed.

CVE-2015-1791: Fixed a race condition in NewSessionTicket creation.

CVE-2015-3216: Fixed a potential crash in ssleay_rand_bytes due to
locking regression.

fixed a timing side channel in RSA decryption (bnc#929678)

Additional changes :

In the default SSL cipher string EXPORT ciphers are now disabled. This
will only get active if applications get rebuilt and actually use this
string. (bnc#931698)

Added the ECC ciphersuites to the DEFAULT cipher class (bnc#879179)

Note that Tenable Network Security has extracted the preceding
description block directly from the SUSE security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
