DESCRIPTION:
Thierry Zoller has reported some vulnerabilities in Avira Antivir,
which can be exploited by malicious people to cause a DoS (Denial of
Service).

The vulnerabilities are caused due to errors in the handling of RAR
files. These can be exploited to crash an affected program via a
specially crafted RAR archive.

SOLUTION:
Update the scanning engine to versions 7.9.0.54, 8.2.0.54, or later.
