CVE-2021-25176: Siemens JT2Go DXF File Parsing Untrusted Pointer Dereference Remote Code Execution Vulnerability
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).
Other sources
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.
