Media Players

C5. Media Players

C5.1 Description

Media players are popularly used and have an install base of millions of systems. Content is downloaded in the form of multimedia files such as movies, video or music. This content is embedded into Web pages, presentations, or integrated into multimedia applications.

Media players can end up on systems through default installations or bundled with other software. Typically browsers are set up to "conveniently" download and open media files without requiring user interaction. They are also downloaded by users on corporate networks to facilitate transfer of multimedia content to their mobile devices.

A number of vulnerabilities have been discovered in various media players over the last year. Many of these vulnerabilities allow a malicious webpage or a media file to completely compromise a user's system without requiring much user interaction. The user's system can be compromised simply upon visiting a malicious webpage. Hence, these vulnerabilities can be exploited to install malicious software like spyware, Trojans, adware or keyloggers on users' systems. Exploit code is publicly available in many instances.

Some of the more popular media players include:

  • Windows: Windows Media Player, RealPlayer, Apple Quicktime, Winamp, iTunes
  • Mac OS: RealPlayer, Quicktime, iTunes
  • Linux/Unix: RealPlayer, Helix Player

C5.4 How to Determine If You Are Vulnerable

If you run any of these players, and you are not running the most recent version with all applicable patches, you are vulnerable to the associated attacks. Periodic system reviews of installed software can be used to track unintended media player installations as well as rogue user installations.

C5.5 How to Protect Against Media Player Vulnerabilities

Following are some common approaches to protect against these vulnerabilities:

  • Keep the media players updated with all the latest patches. Most players support updating via the help or tools menus.
  • Carefully review default installations of operating systems and other products to ensure they do not include unwanted media players. Configure operating systems and browsers to prevent unintentional installation.
  • Use Intrusion Prevention/Detection Systems and Anti-virus and Malware Detection Software to block malicious media files.
  • On corporate desktops limit installation of user downloaded software whenever possible. This will allow for better patch management and vulnerability management.
  • Don't install media players on systems where media is not to be played (e.g. servers)
