28 May 2013
Several security issues were fixed in Tomcat.
- tomcat6 - Servlet and JSP engine
- tomcat7 - Servlet and JSP engine
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.
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.
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)
The problem can be corrected by updating your system to the following package versions:
In general, a standard system update will make all the necessary changes.
