https://notcve.org/view.php?id=CVE-2021-32946
An improper check for unusual or exceptional conditions issue exists within the parsing DGN files from Drawings SDK (Version 2022.4 and prior) resulting from the lack of proper validation of the user-supplied data. This may result in several of out-of-bounds problems and allow attackers to cause a denial-of-service condition or execute code in the context of the current process. Se presenta un problema de comprobación inapropiada de condiciones inusuales o excepcionales en el análisis de archivos DGN de Drawings SDK (Versiones 2022.4 y anteriores) resultando en una falta de comprobación apropiada de los datos suministrados por el usuario. Esto puede resultar en varios problemas fuera de límites y permitir a atacantes causar una condición de denegación de servicio o ejecutar código en el contexto del proceso actual 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. • https://cert-portal.siemens.com/productcert/pdf/ssa-155599.pdf https://cert-portal.siemens.com/productcert/pdf/ssa-938030.pdf https://us-cert.cisa.gov/ics/advisories/icsa-21-159-02 https://www.zerodayinitiative.com/advisories/ZDI-21-983 https://www.zerodayinitiative.com/advisories/ZDI-21-985 • CWE-754: Improper Check for Unusual or Exceptional Conditions •

https://notcve.org/view.php?id=CVE-2021-32938
Drawings SDK (All versions prior to 2022.4) are vulnerable to an out-of-bounds read due to parsing of DWG files 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 allows attackers to cause a denial-of service condition or read sensitive information from memory. Drawings SDK (todas las versiones anteriores a 2022.4) es vulnerable a una lectura fuera de límites debido al análisis de archivos DWG 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 permite a atacantes causar una condición de denegación de servicio o leer información confidencial de la 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.

https://notcve.org/view.php?id=CVE-2021-32940
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.
