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


Synopsis :

The remote openSUSE host is missing a security update.

Description :

This update for openssl fixes the following issues :

Security fixes :

- CVE-2015-3194: The signature verification routines will
crash with a NULL pointer dereference if presented with
an ASN.1 signature using the RSA PSS algorithm and
absent mask generation function parameter. Since these
routines are used to verify certificate signature
algorithms this can be used to crash any certificate
verification operation and exploited in a DoS attack.
Any application which performs certificate verification
is vulnerable including OpenSSL clients and servers
which enable client authentication. (bsc#957815)

- CVE-2015-3195: When presented with a malformed
X509_ATTRIBUTE structure OpenSSL would leak memory. This
structure is used by the PKCS#7 and CMS routines so any
application which reads PKCS#7 or CMS data from
untrusted sources is affected. SSL/TLS is not affected.
(bsc#957812)

- CVE-2015-3196: If PSK identity hints are received by a
multi-threaded client then the values were wrongly
updated in the parent SSL_CTX structure. This could
result in a race condition potentially leading to a
double free of the identify hint data. (bsc#957813)

Non security bugs fixed :

- Improve S/390 performance on IBM z196 and z13
(bsc#954256)
