Descriptions

An issue was discovered in Open Design Alliance Drawings SDK before 2021.12. A memory corruption vulnerability exists when reading malformed DGN files. It can allow attackers to cause a crash, potentially enabling denial of service (Crash, Exit, or Restart).

Se detectó un problema en Open Design Alliance Drawings SDK versiones anteriores a 2021.12. Se presenta una vulnerabilidad de corrupción de la memoria al leer archivos DGN malformados. Puede permitir a los atacantes causar un bloqueo, 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 DGN files. The issue results from the lack of proper validation of user-supplied data, which can result in a memory corruption condition. An attacker can leverage this vulnerability to execute code in the context of the current process.
