Debian Security Advisory DSA 2897-1 (tomcat7 - security update)

Published: 2014-04-07 22:00:00
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:L/Au:N/C:P/I:P/A:P

Solution Type:
Vendor Patch

Affected Versions:
tomcat7 on Debian Linux

Technical Details:
Apache Tomcat implements the Java Servlet and the JavaServer Pages (JSP) specifications from Sun Microsystems, and provides a 'pure Java' HTTP web server environment for Java code to run.

Recommendations:
For the stable distribution (wheezy), these problems have been fixed in version 7.0.28-4+deb7u1. For the testing distribution (jessie), these problems have been fixed in version 7.0.52-1. For the unstable distribution (sid), these problems have been fixed in version 7.0.52-1. We recommend that you upgrade your tomcat7 Linux Distribution Packages.

Summary:
Multiple security issues were found in the Tomcat servlet and JSP engine: CVE-2013-2067 FORM authentication associates the most recent request requiring authentication with the current session. By repeatedly sending a request for an authenticated resource while the victim is completing the login form, an attacker could inject a request that would be executed using the victim's credentials. CVE-2013-2071 A runtime exception in AsyncListener.onComplete() prevents the request from being recycled. This may expose elements of a previous request to a current request. CVE-2013-4286 Reject requests with multiple content-length headers or with a content-length header when chunked encoding is being used. CVE-2013-4322 When processing a request submitted using the chunked transfer encoding, Tomcat ignored but did not limit any extensions that were included. This allows a client to perform a limited denial of service by streaming an unlimited amount of data to the server. CVE-2014-0050 Multipart requests with a malformed Content-Type header could trigger an infinite loop causing a denial of service.

Detection Method:
This check tests the installed software version using the apt Linux Distribution Package manager.

Detection Type:
Linux Distribution Package

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
