| Beschreibung: | Summary:
Multiple security issues were found
in the Tomcat servlet and JSP engine:
CVE-2013-2067
FORM authentication associates the most recent request requiring
authentication with the current session. By repeatedly sending a request
for an authenticated resource while the victim is completing the login
form, an attacker could inject a request that would be executed using the
victim's credentials.
CVE-2013-2071
A runtime exception in AsyncListener.onComplete() prevents the request from
being recycled. This may expose elements of a previous request to a current
request.
CVE-2013-4286
Reject requests with multiple content-length headers or with a content-length
header when chunked encoding is being used.
CVE-2013-4322
When processing a request submitted using the chunked transfer encoding,
Tomcat ignored but did not limit any extensions that were included. This allows
a client to perform a limited denial of service by streaming an unlimited amount
of data to the server.
CVE-2014-0050
Multipart requests with a malformed Content-Type header could trigger an
infinite loop causing a denial of service.
