Description Agostino Sarubbo gentoo-dev 2013-05-11 12:26:10 UTC
From :

A denial of service flaw was found in the way chunked transfer encoding input filter of Apache 
Tomcat, an Apache Servlet/JSP Engine, processed CRLF sequences at the end of data chunks in certain 
circumstances. When the chunked transfer encoding was enabled, a remote attacker could issue a 
specially-crafted request that, when processed would lead to (limited) denial of service of the 
Apache Tomcat server.

Relevant upstream patch:
* for Apache Tomcat 6.x: 

* for Apache Tomcat 7:x:
Comment 1 Agostino Sarubbo gentoo-dev 2013-05-11 12:26:15 UTC
From :

A session fixation flaw was found in the way FormAuthenticator module of Apache Tomcat, an Apache 
Servlet/JSP Engine, performed authentication requests management in certain circumstances (the most 
recent authentication request was associated with current user's session). An attacker could use 
this flaw to inject (and possibly successfully to complete) an authentication request, that would 
be executed using the credentials of the victim.

Relevant upstream patch:
* for Apache Tomcat 6.x:
* for Apache Tomcat 7.x:
Comment 2 Agostino Sarubbo gentoo-dev 2013-05-11 12:26:18 UTC
From :

An information disclosure flaw was found in the way asynchronous context implementation of Apache 
Tomcat, an Apache Servlet/JSP Engine, performed request information management in certain 
circumstances (formerly certain elements of a previous request might have been exposed to the 
current request). If an application used AsyncListeners that threw RuntimeExceptions, a remote 
attacker could use this flaw to possibly obtain sensitive information.

Upstream bug report:

Relevant upstream patch (including testcase):

@maintainer(s): after the bump, in case we need to stabilize the package, please say explicitly if it is ready for the stabilization or not.
Comment 3 Chris Reffett (RETIRED) gentoo-dev Security 2013-07-07 03:13:13 UTC
First one fixed since 7.0.40/doesn't seem to affect 6.0.x, second one fixed in 7.0.33/6.0.37. Not sure which revisions were the first to fix the third issue, but the latest 6.0.x and 7.0.x have the requisite fixes. @java team: please ack stabilization.
Comment 4 GLSAMaker/CVETool Bot gentoo-dev 2013-08-29 22:49:20 UTC
CVE-2013-2071 (
  java/org/apache/catalina/core/ in Apache Tomcat 7.x
  before 7.0.40 does not properly handle the throwing of a RuntimeException in
  an AsyncListener in an application, which allows context-dependent attackers
  to obtain sensitive request information intended for other applications in
  opportunistic circumstances via an application that records the requests
  that it processes.

CVE-2013-2067 (
  java/org/apache/catalina/authenticator/ in the form
  authentication feature in Apache Tomcat 6.0.21 through 6.0.36 and 7.x before
  7.0.33 does not properly handle the relationships between authentication
  requirements and sessions, which allows remote attackers to inject a request
  into a session by sending this request during completion of the login form,
  a variant of a session fixation attack.
Comment 5 GLSAMaker/CVETool Bot gentoo-dev 2013-08-30 00:03:20 UTC
CVE-2012-3544 (
  Apache Tomcat 6.x before 6.0.37 and 7.x before 7.0.30 does not properly
  handle chunk extensions in chunked transfer coding, which allows remote
  attackers to cause a denial of service by streaming data.
