Security Advisory

1) Buffer overflow

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to boundary error when processing HTML code. A remote unauthenticated attacker can create a specially crafted web page, trick the victim into visiting it, trigger memory corruption and execute arbitrary code on the target system.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Remediation

Install updates from vendor's website.
