Summary
SSA-039007: Heap-based Buffer Overflow Vulnerability in User Management Component (UMC)

Notes

Summary
Siemens User Management Component (UMC) is affected by a heap-based buffer overflow vulnerability which could allow an unauthenticated remote attacker arbitrary code execution. Siemens has released new versions for several affected products and recommends to update to the latest versions. Siemens is preparing further fix versions and recommends specific countermeasures for products where fixes are not, or not yet available.
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
