Descriptions
An out-of-bounds read issue exists in the DWG file-recovering procedure in the Drawings SDK (All versions prior to 2022.5) resulting from the lack of proper validation of user-supplied data. This can result in a read past the end of an allocated buffer and allow attackers to cause a denial-of-service condition or read sensitive information from memory locations.
Se presenta un problema de lectura fuera de límites en el procedimiento de recuperación de archivos DWG en Drawings SDK (todas las versiones anteriores a 2022.4) resultando en una falta de comprobación apropiada de los datos suministrados por el usuario. Esto puede resultar en una lectura más allá del final de un búfer asignado y permitir a atacantes causar una condición de denegación de servicio o leer información confidencial de las ubicaciones de memoria
This vulnerability allows remote attackers to disclose sensitive information on affected installations of Siemens JT2Go. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file.
The specific flaw exists within the parsing of DWG files. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated buffer. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process.
