SSA-976324: Multiple IGS File Parsing Vulnerabilities in PS/IGES Parasolid Translator Component before V27.1.215

Publication Date:	2024-05-14
Last Update:	2024-05-14
Current Version:	V1.0
CVSS v3.1 Base Score:	7.8
CVSS v4.0 Base Score:	7.3

SUMMARY

PS/IGES Parasolid Translator Component contains multiple file parsing vulnerabilities that could be triggered when the application reads files in IGS 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 PS/IGES Parasolid Translator Component and recommends to update to the latest version.
