Ubuntu Security Notice USN-1841-1
May 28, 2013

tomcat6, tomcat7 vulnerabilities
==========================================================================

A security issue affects these releases of Ubuntu and its derivatives:

- Ubuntu 13.04
- Ubuntu 12.10
- Ubuntu 12.04 LTS
- Ubuntu 10.04 LTS

Summary:

Several security issues were fixed in Tomcat.

Software Description:
- tomcat7: Servlet and JSP engine
- tomcat6: Servlet and JSP engine

Details:

It was discovered that Tomcat incorrectly handled certain requests
submitted using chunked transfer encoding. A remote attacker could use this
flaw to cause the Tomcat server to stop responding, resulting in a denial
of service. This issue only affected Ubuntu 10.04 LTS and Ubuntu 12.04 LTS.
(CVE-2012-3544)

It was discovered that Tomcat incorrectly handled certain authentication
requests. A remote attacker could possibly use this flaw to inject a
request that would get executed with a victim's credentials. This issue
only affected Ubuntu 10.04 LTS, Ubuntu 12.04 LTS, and Ubuntu 12.10.
(CVE-2013-2067)

It was discovered that Tomcat sometimes exposed elements of a previous
request to the current request. This could allow a remote attacker to
possibly obtain sensitive information. This issue only affected Ubuntu
12.10 and Ubuntu 13.04. (CVE-2013-2071)

Update instructions:

The problem can be corrected by updating your system to the following
package versions:

Ubuntu 13.04:
libtomcat7-java 7.0.35-1~exp2ubuntu1.1

Ubuntu 12.10:
libtomcat7-java 7.0.30-0ubuntu1.2

Ubuntu 12.04 LTS:
libtomcat6-java 6.0.35-1ubuntu3.3

Ubuntu 10.04 LTS:
libtomcat6-java 6.0.24-2ubuntu1.13

In general, a standard system update will make all the necessary changes.
