Name of the Vulnerable Software and Affected Versions Bentley MicroStation CONNECT version 10.16.02.34

Description This issue allows remote attackers to execute arbitrary code on affected installations. User interaction is required, where the target must visit a malicious page or open a malicious file. The flaw exists within the parsing of DGN files, where crafted data can trigger a write past the end of an allocated buffer, allowing an attacker to execute code in the context of the current process.
