CVE-2021-27040: ICONICS GENESIS64 DWG File Parsing Out-Of-Bounds Read Information Disclosure Vulnerability

Published Jun 25, 2021
·
Updated

A maliciously crafted DWG file can be forced to read beyond allocated boundaries when parsing the DWG file. This vulnerability can be exploited to execute arbitrary code.

Other sources

This vulnerability allows remote attackers to disclose sensitive information on affected installations of ICONICS GENESIS64. 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 parsing of DWG files. The issue results from the lack of proper validation of user-supplied data, which can result in a read past the end of an allocated data structure. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of the current process.
