An Out-of-Bounds Write vulnerability exists when reading a DXF or DWG file using Open Design Alliance Drawings SDK before 2022.11. The specific issue exists within the parsing of DXF and DWG files. Crafted data in a DXF or DWG file (an invalid number of properties) can trigger a write operation past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.

- SSA-301589SSA-301589: Multiple File Parsing Vulnerabilities in Solid Edge, JT2Go and Teamcenter Visualization2022-02-08csaf · siemens_psirtDE
Siemens has released updates for JT2Go, Solid Edge and Teamcenter Visualization to fix multiple file parsing vulnerabilities. If a user is tricked to open a malicious file (crafted as PDF, DXF or PAR) with any of the affected products, this could lead the application to crash or potentially lead to arbitrary code execution. Siemens has released updates for some of the affected products and recommends to update to the latest versions. Siemens is preparing further updates and recommends specific countermeasures for products where updates are not yet available.
- SSA-491245SSA-491245: Multiple File Parsing Vulnerabilities in Solid Edge2023-02-14csaf · siemens_psirtDE
Solid Edge is affected by multiple memory corruption vulnerabilities that could be triggered when the application reads specially crafted files in various formats such as X_B, DWG, DXF, STL, STP, SLDPRT and PAR format. If a user is tricked to open a malicious file with the affected applications, an attacker could leverage the vulnerability to crash the application, extract data or potentially lead to arbitrary code execution. Siemens has released updates for the affected products and recommends to update to the latest versions.
