Date: Mon, 10 Apr 2017 20:14:34 +0100 From: Mark Thomas <markt@...che.org> To: oss-security@...ts.openwall.com Subject: [SECURITY] CVE-2017-5651 Apache Tomcat Information Disclosure CVE-2017-5651 Apache Tomcat Information Disclosure Severity: Important Vendor: The Apache Software Foundation Versions Affected: Apache Tomcat 9.0.0.M1 to 9.0.0.M18 Apache Tomcat 8.5.0 to 8.5.12 Apache Tomcat 8.0.x and earlier are not affected Description: The refactoring of the HTTP connectors for 8.5.x onwards, introduced a regression in the send file processing. If the send file processing completed quickly, it was possible for the Processor to be added to the processor cache twice. This could result in the same Processor being used for multiple requests which in turn could lead to unexpected errors and/or response mix-up. Mitigation: Users of the affected versions should apply one of the following mitigations: - Upgrade to Apache Tomcat 9.0.0.M19 or later - Upgrade to Apache Tomcat 8.5.13 or later Credit: This issue was reported publicly as Bug 60918  and the security implications identified by the Tomcat security team. History: 2017-04-10 Original advisory References:  https://bz.apache.org/bugzilla/show_bug.cgi?id=60918  http://tomcat.apache.org/security-9.html  http://tomcat.apache.org/security-8.html
