Releases
Packages
- tomcat6 - Servlet and JSP engine
Details
It was discovered that Tomcat incorrectly handled data with malformed
chunked transfer coding. 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. (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.
(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)
