RealNetworks products vulnerable to buffer overflow via specially crafted flash media file

Description

### Overview Numerous RealNetworks products are vulnerable to a buffer overflow that may allow a remote attacker to execute arbitrary code on a vulnerable system. ### Description **RealNetworks RealPlayer** RealNetworks [RealPlayer](<http://www.real.com/>) is a multimedia application that allows users to view local and remote audio/video content. **SWF File format** The SWF file format is used by Macromedia Flash multimedia files. See the Macromedia [File Format Specification FAQ](<http://www.macromedia.com/licensing/developer/fileformat/faq/>) for more information on the SWF file format. **The Problem** Numerous RealNetworks products fail to properly validate SWF files allowing a buffer overflow to occur. By persuading a user to access a specially crafted SWF file with RealPlayer, a remote attacker may be able to execute arbitrary code. **Considerations** A complete list of affected software is available in the [RealNetwork Security Update](<http://service.real.com/realplayer/security/03162006_player/en/>) for March 2006. --- ### Impact By convincing a user to open a specially crafted SWF file with RealPlayer, a remote unauthenticated attacker can execute arbitrary code on a vulnerable system. --- ### Solution **Patch RealPlayer** Apply the patches supplied in the [RealNetwork Security Update](<http://service.real.com/realplayer/security/03162006_player/en/>) for March 2006. --- **Disable RealPlayer in your web browser** An attacker may be able to exploit this vulnerability by embedding the crafted SWF file in a webpage and convincing a user to access that page. 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.
