Overview
RealPlayer contains a stack buffer overflow in the handling of playlist names, which can allow a remote, unauthenticated attacker to execute arbitrary code on a vulnerable system.
Description
RealNetworks RealPlayer is a multimedia application that allows users to view local and remote audio/video content. The RealPlayer Database Component, which is provided by MPAMedia.dll, contains a stack buffer overflow in the handling of playlist names. The RealPlayer IERPCtl ActiveX control, which is provided by ierpplug.dll, can be used to import a local file into a specified playlist in RealPlayer. This can be used to trigger the buffer overflow vulnerability. The ActiveX control is present in RealPlayer version 9 (RealOne Player) and later. |
Impact
By convincing a user to view a specially crafted HTML document (e.g., a web page or an HTML email message or attachment), a remote, unauthenticated attacker may be able to execute arbitrary code with the privileges of the user on a vulnerable system. |
Solution
Apply an update Please see the Security Update from RealNetworks. The update will provide newer versions of the RealPlayer Database Component for RealPlayer 10.5 and RealPlayer 11 beta. Users with RealOne Player, RealOne Player v2, or RealPlayer 10 should first update to RealPlayer 10.5 or later and then apply the security update. |
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\ActiveX Compatibility\{FDC7A535-4070-4B92-A0EA-D9994BCC0DC5}] "Compatibility Flags"=dword:00000400 Disabling ActiveX controls in the Internet Zone (or any zone used by an attacker) appears to prevent exploitation of this and other ActiveX vulnerabilities. Instructions for disabling ActiveX in the Internet Zone can be found in the "Securing Your Web Browser" document. |
