This indicates an attack attempt to exploit Remote Code Execution Vulnerability in Microsoft Windows.
The vulnerability is due to an error in the vulnerable application when handling a maliciously crafted VCF file. Crafted data in a VCF file can cause Windows to display a dangerous hyper link. A remote attacker may be able to exploit this to execute arbitrary code within the context of the application, via a crafted VCF file and user interaction on the dangerous hyper link.
System Compromise: Remote attackers can gain control of vulnerable systems.
Currently we are not aware any vendor provided patch to address this issue.
