Title:	Debian: Security Advisory (DLA-623-1)
Summary:	The remote host is missing an update for the Debian 'tomcat7' package(s) announced via the DLA-623-1 advisory.
Description:	Summary: The remote host is missing an update for the Debian 'tomcat7' package(s) announced via the DLA-623-1 advisory. Vulnerability Insight: Dawid Golunski from legalhackers.com discovered that Debian's version of Tomcat 7 was vulnerable to a local privilege escalation. Local attackers who have gained access to the server in the context of the tomcat7 user through a vulnerability in a web application were able to replace the file with a symlink to an arbitrary file. The full advisory can be found at In addition this security update also fixes Debian bug #821391. File ownership in /etc/tomcat7 will no longer be unconditionally overridden on upgrade. As another precaution the file permissions of Debian specific configuration files in /etc/tomcat7 were changed to 640 to disallow world readable access. For Debian 7 Wheezy, these problems have been fixed in version 7.0.28-4+deb7u6. We recommend that you upgrade your tomcat7 packages.

Solution: Please install the updated package(s). CVSS Score: 7.2 CVSS Vector: AV:L/AC:L/Au:N/C:C/I:C/A:C
