Summary
SSA-426509: Multiple Local Code Execution Vulnerabilities in Questa and ModelSim

Notes

Summary
Questa and ModelSim (incl. OEM Editions) are affected by multiple vulnerabilities that could allow a local attacker to inject arbitrary code and escalate privileges. Siemens has released new versions for the affected products and recommends to update to the latest versions.
General Recommendations
