RHEL 7 : tomcat (RHSA-2017:3081)

high Nessus Plugin ID 104251

Language:

Synopsis

The remote Red Hat host is missing one or more security updates for tomcat.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:3081 advisory.

Apache Tomcat is a servlet container for the Java Servlet and JavaServer Pages (JSP) technologies.

Security Fix(es):

* A vulnerability was discovered in Tomcat's handling of pipelined requests when Sendfile was used. If sendfile processing completed quickly, it was possible for the Processor to be added to the processor cache twice. This could lead to invalid responses or information disclosure. (CVE-2017-5647)

* Two vulnerabilities were discovered in Tomcat where if a servlet context was configured with readonly=false and HTTP PUT requests were allowed, an attacker could upload a JSP file to that context and achieve code execution. (CVE-2017-12615, CVE-2017-12617)

* A vulnerability was discovered in Tomcat where the CORS Filter did not send a Vary: Origin HTTP header. This potentially allowed sensitive data to be leaked to other visitors through both client-side and server-side caches. (CVE-2017-7674)

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 tomcat package based on the guidance in RHSA-2017:3081.
