SSA-064222: Multiple File Parsing Vulnerabilities in Simcenter Femap before V2406

Publication Date:	2024-07-09
Last Update:	2024-07-09
Current Version:	V1.0
CVSS v3.1 Base Score:	7.8
CVSS v4.0 Base Score:	7.3

SUMMARY

Simcenter Femap contains multiple file parsing vulnerabilities that could be triggered when the application reads files in IGS, BDF or BMP file formats. If a user is tricked to open a malicious file with any of the affected products, this could lead the application to crash or potentially lead to arbitrary code execution.

Siemens has released a new version for Simcenter Femap and recommends to update to the latest version.
