-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Important: tomcat security update Advisory ID: RHSA-2017:3081-01 Product: Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2017:3081 Issue date: 2017-10-29 CVE Names: CVE-2017-12615 CVE-2017-12617 CVE-2017-5647 CVE-2017-7674 ===================================================================== 1. Summary: An update for tomcat is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Important. 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. 2. Relevant releases/architectures: Red Hat Enterprise Linux Client (v. 7) - noarch Red Hat Enterprise Linux Client Optional (v. 7) - noarch Red Hat Enterprise Linux ComputeNode (v. 7) - noarch Red Hat Enterprise Linux ComputeNode Optional (v. 7) - noarch Red Hat Enterprise Linux Server (v. 7) - noarch Red Hat Enterprise Linux Server Optional (v. 7) - noarch Red Hat Enterprise Linux Workstation (v. 7) - noarch Red Hat Enterprise Linux Workstation Optional (v. 7) - noarch 3. Description: 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) 4.
