- SSA-328042SSA-328042: File Parsing Vulnerabilities in OBJ Translator in NX2021-11-09csaf · siemens_psirtDE
Siemens NX is affected by two vulnerabilities that could be triggered when the application reads OBJ files. If a user is tricked to open a malicious file with the affected application, this could lead to an access violation, and potentially also to arbitrary code execution on the target host system. Siemens has released updates for the NX and recommends to update to the latest version. Siemens recommends to avoid opening of untrusted files from unknown sources.
- SSA-728618SSA-728618: Multiple Vulnerabilities in Solid Edge before SE2021MP82021-09-28csaf · siemens_psirtDE
Siemens has released a new version for Solid Edge that fixes multiple file parsing vulnerabilities which could be triggered when the application reads files in IFC, JT or OBJ formats. If a user is tricked to opening a malicious file using the affected application this could lead the application to crash, or potentially arbitrary code execution on the target host system. Siemens recommends to update to the latest version and to limit opening of files from unknown sources in the affected products.
