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


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

A NULL pointer derefernce flaw was found in the way OpenSSL verified
signatures using the RSA PSS algorithm. A remote attacked could
possibly use this flaw to crash a TLS/SSL client using OpenSSL, or a
TLS/SSL server using OpenSSL if it enabled client authentication.
(CVE-2015-3194)

A memory leak vulnerability was found in the way OpenSSL parsed PKCS#7
and CMS data. A remote attacker could use this flaw to cause an
application that parses PKCS#7 or CMS data from untrusted sources to
use an excessive amount of memory and possibly crash. (CVE-2015-3195)

A race condition flaw, leading to a double free, was found in the way
OpenSSL handled pre-shared key (PSK) identify hints. A remote attacker
could use this flaw to crash a multi-threaded SSL/TLS client using
OpenSSL. (CVE-2015-3196)

For the update to take effect, all services linked to the OpenSSL
library must be restarted, or the system rebooted.
