Vulnerability Note VU#298651

RealNetworks RealPlayer Shockwave Flash (SWF) file vulnerability

Overview

RealNetworks RealPlayer fails to properly handle frames within Shockwave Flash (SWF) files, which can allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.

I. Description

The RealNetworks RealPlayer application provides support for the SWF file format. A buffer overflow exists in the way that the RealPlayer handles specially crafted SWF files. A remote, unauthenticated attacker with the ability to supply a specially crafted SWF file could exploit this vulnerability to execute arbitrary code on an affected system.

II. Impact

By convincing a user to view a specially crafted HTML document (e.g., a web page or an HTML email message or attachment), an attacker may be able to execute arbitrary code with the privileges of the user.

III. Solution

Apply an update

This issue is addressed in RealPlayer 11.0.3. Please see the RealPlayer security update for more details.
