The Expression Language (EL) implementation in Apache Tomcat 6.x before 6.0.44, 7.x before 7.0.58, and 8.x before 8.0.16 does not properly consider the possibility of an accessible interface implemented by an inaccessible class, which allows attackers to bypass a SecurityManager protection mechanism via a web application that leverages use of incorrect privileges during EL evaluation.

Affected: Ubuntu:14.04:LTS: tomcat7

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. (CVE-2014-0119)

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. (CVE-2014-0227)

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 a limited denial of service. This issue only affected Ubuntu 14.04 LTS. (CVE-2014-0230)

It was discovered that the Tomcat Expression Language (EL) implementation incorrectly handled accessible interfaces implemented by inaccessible classes. An attacker could possibly use this issue to bypass a SecurityManager protection mechanism. (CVE-2014-7810)
