Vulnerability from csaf_siemens - Published: 2021-07-13 00:00 - Updated: 2021-07-13 00:00
Summary
SSA-209268: Multiple JT File Parsing Vulnerabilities in JT Utilities before V13.0.2.0

Notes

Summary
Siemens has released version V13.0.2.0 for JT Utilities to fix multiple vulnerabilities that could be triggered when reading JT files. Siemens recommends to update to the latest version, which contains solutions to all the vulnerabilities listed in this advisory. Standing recommendation is to avoid opening of untrusted files from unknown sources in the affected product, as this generally mitigates the risk of exploitation of this class of vulnerabilities for any product release.
General Recommendations
As a general security measure, Siemens strongly recommends to protect network access to devices with appropriate mechanisms. In order to operate the devices in a protected IT environment, Siemens recommends to configure the environment according to Siemens' operational guidelines for Industrial Security (Download: https://www.siemens.com/cert/operational-guidelines-industrial-security), and to follow the recommendations in the product manuals. Additional information on Industrial Security by Siemens can be found at: https://www.siemens.com/industrialsecurity
