Description

This vulnerability allows remote attackers to execute arbitrary code on affected installations of Corel CorelDRAW Graphics Suite 23.5.0.506. 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 CGM files.
