In response to a report of a GT.M vulnerability, we have produced a GT.M security advisory (see http://www.fidelityinfoservices.com/NR/rdonlyres/0CABD5C8-82B9-41E9-B9C1-5D477E36E306/0/0810232cS9I10002703gtmsecshr.pdf\). This vulnerability can theoretically allow someone who has programmer access to GT.M in a UNIX/Linux system to escalate privileges to root, but should not otherwise expose a properly secured production system.
Please read the advisory at your earliest convenience, and take action as appropriate for your environment(s). Please do contact me with any questions, comments or concerns.
