HP Security Bulletin HPSBUX03561 1 - Potential security vulnerabilities has been identified in the HP-UX Tomcat-based Servlet Engine. These vulnerabilities could be exploited remotely to create Denial of Service (DoS), access restriction bypass, unauthorized read access to files, arbitrary code execution, and execution of arbitrary code with privilege elevation. Revision 1 of this advisory.

Red Hat Security Advisory 2015-2661-01 - Red Hat JBoss Web Server is a fully integrated and certified set of components for hosting Java web applications. It is comprised of the Apache HTTP Server, the Apache Tomcat Servlet container, Apache Tomcat Connector, JBoss HTTP Connector, Hibernate, and the Tomcat Native library. It was found that Tomcat would keep connections open after processing requests with a large enough request body. A remote attacker could potentially use this flaw to exhaust the pool of available connections and prevent further, legitimate connections to the Tomcat server.

Ubuntu Security Notice 2654-1 - It was discovered that the Tomcat XML parser incorrectly handled XML External Entities (XXE). A remote attacker could possibly use this issue to read arbitrary files. This issue only affected Ubuntu 14.04 LTS. It was discovered that Tomcat incorrectly handled data with malformed chunked transfer coding. A remote attacker could possibly use this issue to conduct HTTP request smuggling attacks, or cause Tomcat to consume resources, resulting in a denial of service. This issue only affected Ubuntu 14.04 LTS. Various other issues were also addressed.

Ubuntu Security Notice 2655-1 - It was discovered that Tomcat incorrectly handled data with malformed chunked transfer coding. A remote attacker could possibly use this issue to conduct HTTP request smuggling attacks, or cause Tomcat to consume resources, resulting in a denial of service. It was discovered that Tomcat incorrectly handled HTTP responses occurring before the entire request body was finished being read. A remote attacker could possibly use this issue to cause memory consumption, resulting in a denial of service. Various other issues were also addressed.

When a response for a request with a request body is returned to the user agent before the request body is fully read, by default Tomcat swallows the remaining request body so that the next request on the connection may be processed. There was no limit to the size of request body that Tomcat would swallow. This permitted a limited denial of service as Tomcat would never close the connection and a processing thread would remain allocated to the connection. Versions affected include Apache Tomcat 8.0.0-RC1 to 8.0.8, 7.0.0 to 7.0.54, and 6.0.0 to 6.0.43.

FreeBSD Security Advisory - The Transmission Control Protocol (TCP) of the TCP/IP protocol suite provides a connection-oriented, reliable, sequence-preserving data stream service. New TCP connections are initiated using special SYN flag in a datagram. Sequencing of data is controlled by 32-bit sequence numbers, that start with a random value and are increased using modulo 2**32 arithmetic. TCP endpoints maintain a window of expected, and thus allowed, sequence numbers for a connection. When a segment with the SYN flag for an already existing connection arrives, the TCP stack tears down the connection, bypassing a check that the sequence number in the segment is in the expected window. An attacker who has the ability to spoof IP traffic can tear down a TCP connection by sending only 2 packets, if they know both TCP port numbers. In case one of the two port numbers is unknown, a successful attack requires less than 2**17 packets spoofed, which can be generated within less than a second on a decent connection to the Internet.
