Numerous RealNetworks products do not properly handle chunked data. This vulnerability may allow a remote attacker to execute arbitrary code on a vulnerable system.
RealNetworks RealPlayer
RealNetworks RealPlayer is a multimedia application that allows users to view local and remote audio/video content.
Chunked Encoding
Chunked encoding is a means to transfer variable-sized units of data (called chunks) from a web client to a web server.
The Problem
Numerous RealNetworks products fail to properly handle file chunks allowing a buffer overflow to occur. By persuading a user to access a RealPlayer file hosted on a malicious server, a remote attacker may be able to execute arbitrary code.
Considerations
A complete list of affected software is available in the RealNetwork Security Update for March 2006.
By convincing a user to open RealPlayer file hosted on a malicious server, a remote unauthenticated attacker can execute arbitrary code.
Patch RealPlayer
Apply the patches supplied in the RealNetwork Security Update for March 2006.
Disable RealPlayer in your web browser
An attacker may be able to exploit this vulnerability by persuading a user to access a RealPlayer file with a web browser. Disabling RealPlayer in the web browser will eliminate this attack vector thereby reducing the chances of exploitation.
To disable RealPlayer in Microsoft Internet Explorer, disable the RealPlayer ActiveX control. In other web browsers, such as Mozilla Firefox, disable the RealPlayer plugin.
