Synopsis :

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

Description :

From Red Hat Security Advisory 2017:2335 :

An update for pki-core is now available for Red Hat Enterprise Linux
7.

Red Hat Product Security has rated this update as having a security
impact of Moderate. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

Red Hat Certificate System is an enterprise software system designed
to manage enterprise public key infrastructure (PKI) deployments. PKI
Core contains fundamental packages required by Red Hat Certificate
System, which comprise the Certificate Authority (CA) subsystem.

Security Fix(es) :

* It was found that a mock CMC authentication plugin with a hard-coded
secret was accidentally enabled by default in the pki-core package. An
attacker could potentially use this flaw to bypass the regular
authentication process and trick the CA server into issuing
certificates. (CVE-2017-7537)

This issue was discovered by Christina Fu (Red Hat).
