RealPlayer file deletion overflow vulnerability

Original Release date: 28 Jul 2008 | Last revised: 28 Jul 2008

Overview

RealPlayer contains a buffer overflow vulnerability that may allow an attacker to execute code on a vulnerable system.

Description

RealPlayer media player that is distributed by RealNetworks. RealPlayer supports streaming and local media.

Per the Zero Day Initiative advisory ZDI-08-046:

    The specific flaw exists in RealPlayer's rjbdll.dll module when handling the deletion of media library files. An attacker could exploit this vulnerability using an ActiveX control {FDC7A535-4070-4B92-A0EA-D9994BCC0DC5} to import a vulnerable file into the user's media library. Upon deletion of this file, an exploitable stack based buffer overflow can be triggered.

Impact

By convincing a user to visit a website, a remote attacker may be able to execute arbitrary code.

Solution

Upgrade
RealPlayer updates for multiple operating systems are available on the RealNetworks support site. Users are encouraged to apply updates as soon as possible.
