Several security issues were fixed in Tomcat.
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)

Several security issues were fixed in Tomcat.
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)
