Debian DLA-622-1 : tomcat6 security update

high Nessus Plugin ID 93544

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Dawid Golunski from legalhackers.com discovered that Debian's version of Tomcat 6 was vulnerable to a local privilege escalation. Local attackers who have gained access to the server in the context of the tomcat6 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

http://legalhackers.com/advisories/Tomcat-Debian-based-Root-Privilege- Es calation-Exploit.txt

For Debian 7 'Wheezy', these problems have been fixed in version 6.0.45+dfsg-1~deb7u2.

We recommend that you upgrade your tomcat6 packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
