MicroStation and MicroStation-based applications may be affected by out-of-bounds read vulnerabilities when opening maliciously crafted IFC files. Exploiting these vulnerabilities could lead to information disclosure.
Using an affected version of MicroStation or MicroStation-based application to open a IFC file containing maliciously crafted data can force an out-of-bounds read. Exploitation of these vulnerabilities within the parsing of IFC files could enable an attacker to read information in the context of the current process.
Affected Versions of Products
|Product||Affected Version||Fixed Version|
|MicroStation||10.16.* and prior versions||10.17.0.* and more recent|
|Bentley View||10.16.* and prior version||10.17.0.* and more recent|
Bentley recommends updating to the latest versions of MicroStation and MicroStation-based applications. As a general best practice, it is also recommended to only open IFC files coming from trusted sources.
