An Out-of-Bounds Read vulnerability exists when reading a DXF file using Open Design Alliance Drawings SDK before 2022.11. The specific issue exists within the parsing of DXF files. Crafted data in a DXF file (an invalid dash counter in line types) can trigger a read past the end of an allocated buffer. An attacker can leverage this vulnerability to execute code in the context of the current process.

- 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.
