> DESCRIPTION:
> Victor Stinner has reported a vulnerability in ClamAV, which can be
> exploited by malicious people to cause a DoS (Denial of Service).
> 
> The vulnerability is caused due to an error within the OLE2 parser
> when handling objects with malformed FAT partitions and large
> property sizes. This can be exploited to cause a DoS due to storage
> and CPU resource consumption by scanning a specially crafted OLE2
> file.
> 
> SOLUTION:
