Multiple vulnerabilities have been found in the file parsing engine.

In detail, the following flaw was determined:

- Divide by Zero in .CHM file parsing.
- Heap Overflow through Integer Overflow in .DOC File Parsing

The .DOC problem can lead to remote arbitrary code execution if an attacker
carefully crafts a file that exploits the aforementioned vulnerabilities.
The vulnerabilities are present in NOD32 Antivirus software versions prior
to the update v.1.1743.

The vulnerabilities were reported on Aug 24 and an update has been issued on
Sep 08 to solve these vulnerabilities through the regular update mechanism.
