ICSA-22-258-02: Siemens Simcenter Femap and Parasolid

CISA's summary

Summary: Simcenter Femap and Parasolid are affected by multiple file parsing vulnerabilities that could be triggered when the application reads files in X_T file formats. If a user is tricked to open a malicious file with the affected applications, an attacker could leverage the vulnerability to perform remote code execution in the context of the current process. Siemens has released updates for the affected products and recommends to update to the latest versions.
