Descriptions
An issue was discovered in Open Design Alliance Drawings SDK before 2021.11. A NULL pointer dereference exists when rendering malformed .DXF and .DWG files. This can allow attackers to cause a crash, potentially enabling a denial of service attack (Crash, Exit, or Restart).
Se detectó un problema en el SDK de dibujos de Open Design Alliance anterior a la versión 2021.11. Existe una derivación de puntero nulo al renderizar archivos .DXF y .DWG malformados. Esto puede permitir a los atacantes provocar un fallo, permitiendo potencialmente un ataque de denegación de servicio (Bloqueo, Salida o Reinicio)
This vulnerability allows remote attackers to execute arbitrary code 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 DXF files. The issue results from the lack of proper validation of a user-supplied value prior to dereferencing it as a pointer. An attacker can leverage this vulnerability to execute code in the context of the current process.
