Some vulnerabilities have been reported in various F-Secure products,
which can be exploited by malware to bypass detection or malicious
people to compromise a vulnerable system.

via a specially crafted ZIP archive to cause a buffer overflow and
execute arbitrary code.
2) An error in the scanning functionality when processing RAR and ZIP
archives can be exploited to prevent malware from being detected.
The vulnerabilities affect the following products:
