CVE-2021-46625: Bentley View JT File Parsing Double Free Remote Code Execution Vulnerability
This vulnerability allows remote attackers to execute arbitrary code on affected installations of Bentley View 10.15.0.75. 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 handling of JT files. The issue results from the lack of validating the existence of an object prior to performing further free operations on the object. An attacker can leverage this vulnerability to execute code in the context of the current process. Was ZDI-CAN-15455.
