Synopsis

The remote Red Hat host is missing one or more security updates for nginx:1.14.

Description

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:2799 advisory.

Nginx is a web server and a reverse proxy server for HTTP, SMTP, POP3 (Post Office Protocol 3) and IMAP protocols, with a focus on high concurrency, performance and low memory usage.

Security Fix(es):

* HTTP/2: large amount of data request leads to denial of service (CVE-2019-9511)

* HTTP/2: flood using PRIORITY frames resulting in excessive resource consumption (CVE-2019-9513)

* HTTP/2: 0-length headers leads to denial of service (CVE-2019-9516)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL nginx:1.14 package based on the guidance in RHSA-2019:2799.
