A vulnerability has been reported in Kaspersky Antivirus, which can be exploited by malicious people to cause a DoS (Denial of Service).
The vulnerability is caused due to an error in the scan engine when processing PE files. This can be exploited to cause an endless loop via a specially crafted PE file containing an invalid value in the "NumberOfRvaAndSizes" field within the Optional Windows Header section.
Successful exploitation prevents further scanning of files.
