MicroStation and MicroStation-based applications may be affected by out-of-bounds read vulnerabilities when opening maliciously crafted DXF files. Exploiting these vulnerabilities could lead to information disclosure.
The following vulnerabilities related to this advisory were discovered by TrendMicro ZDI: ZDI-CAN-16306 and ZDI-CAN-16341. Using an affected version of MicroStation or MicroStation-based application to open a DXF file containing maliciously crafted data can force an out-of-bounds read. Exploitation of these vulnerabilities within the parsing of DXF files could enable an attacker to read information in the context of the current process.
|Applications||Affected Versions||Mitigated Versions|
|MicroStation||10.16.02.* and prior versions||10.16.03.* and more recent|
|Bentley View||10.16.02.* and prior versions||10.16.03.* 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 DXF files coming from trusted sources.
Thanks to Mat Powell of Trend Micro Zero Day Initiative for discovering these vulnerabilities.
