Description Jan Lieskovsky 2013-05-10 12:34:51 UTC 
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.

Comment 1 Jan Lieskovsky 2013-05-10 13:02:20 UTC 
This issue affects the versions of the tomcat package, as shipped with Fedora release of 17 and 18. Please schedule an update.

--

This issue did NOT affect the versions of the tomcat6 packages, as shipped with Fedora release of 17 and 18 (as those versions did not contain the vulnerable code part yet).
Comment 2 Jan Lieskovsky 2013-05-10 13:02:53 UTC 
Created tomcat tracking bugs for this issue

Affects: fedora-all [bug 961806]
