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

The vulnerability is caused due to a double free error related to the
handling of iframes in combination with the "Find keyword"
functionality, which can be exploited by tricking a user into opening
a specially crafted website.

Successful exploitation may allow the execution of arbitrary code,
but requires that the user uses the "Find keyword" functionality (F6)
on a malicious website.

The vulnerability is confirmed in version 6.0.1002. Other versions
may also be affected.

SOLUTION:
Do not browse untrusted websites.

PROVIDED AND/OR DISCOVERED BY:
