Name of the Vulnerable Software and Affected Versions Bentley View version 10.15.0.75

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. Crafted data in a DGN file can trigger a read past the end of an allocated buffer, allowing an attacker to execute code in the context of the current process.

Recommendations For Bentley View version 10.15.0.75, as a temporary workaround, consider restricting the use of DGN file parsing until a patch is available. Avoid opening malicious files or visiting untrusted pages to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
