Language:

New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it is different from CVSS.

VPR Score: 3.6

Synopsis

The remote application is affected by a denial of service vulnerability.

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.

Solution

Upgrade to Tenable SecurityCenter version 5.2.0. Alternatively, apply the relevant patch referenced in the vendor advisory.
