Tenable SecurityCenter OpenSSL ASN.1 Signature Verification Routine DoS (TNS-2016-01)

This script is Copyright (C) 2016-2017 Tenable Network Security, Inc.

Synopsis :

The remote application is affected by a denial of service

Description :

The SecurityCenter application installed on the remote host is
affected by a denial of service vulnerability in the bundled OpenSSL
library. The library is version 1.0.1 or later but prior to 1.0.1q.
It is, therefore, affected by a NULL pointer dereference flaw in file
rsa_ameth.c due to improper handling of ASN.1 signatures that are
missing the PSS parameter. A remote attacker can exploit this to cause
the signature verification routine to crash, resulting in a denial of
service condition.

Risk factor :

Medium / CVSS Base Score : 5.0
