A weakness has been reported in Apache Tomcat, which can be exploited by malicious, local users to disclose sensitive information.

The weakness is caused due to an error within the Jsvc library, which does not drop permissions for the application to access files and directories owned by the super user. This can lead to certain applications being able to access files and directories of the super user.

The weakness is reported in versions 7.0.0 through 7.0.19, 6.0.30 through 6.0.32, and 5.5.32 through 5.5.33.

Solution
Update to versions 5.5.34, 6.0.33, or 7.0.20.
