RHEL 6 / 7 : rh-nginx110-nginx (RHSA-2017:2538)

high Nessus Plugin ID 210313

Synopsis

The remote Red Hat host is missing a security update for rh-nginx110-nginx.

Description

The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2017:2538 advisory.

Nginx is a web server and a reverse proxy server for HTTP, SMTP, POP3 and IMAP protocols, with a strong focus on high concurrency, performance and low memory usage.

Security Fix(es):

* A flaw within the processing of ranged HTTP requests has been discovered in the range filter module of nginx. A remote attacker could possibly exploit this flaw to disclose parts of the cache file header, or, if used in combination with third party modules, disclose potentially sensitive memory by sending specially crafted HTTP requests. (CVE-2017-7529)

Red Hat would like to thank the Nginx project for reporting this issue.

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

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

Solution

Update the RHEL rh-nginx110-nginx package based on the guidance in RHSA-2017:2538.
