DESCRIPTION:
A vulnerability has been reported in PowerArchiver, which potentially
can be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error when handling
"BlackHole" archives. This can be exploited to cause a heap-based
buffer overflow via a specially crafted "BlackHole" archive
containing an overly long filename.

Successful exploitation may allow execution of arbitrary code.

The vulnerability is reported in versions prior to 10.20.21.

SOLUTION:
Update to version 10.20.21.
