Recently, a similar vulnerability in Real Player SMIL parser has been disclosed by iDefense so we can expect to see more exploits for Real Player.Įvery time we receive a new exploit we try to reproduce the user environment so we can launch the exploit to see if our buffer overflow detection technology protects against it. The fact that it is still used by attackers shows that it is still effective, since many users do not regularly update their programs, especially media players such as Real Player. It turns out this is an exploit for a relatively old vulnerability in Real Player discovered in 2005. I have added the URL used by the shellcode to the list of URLs blocked by Sophos’s WS1000 Web Security Appliance. If successfully run, the shellcode uses HTTP to connect to a website in China and download and run a password stealing Trojan targeting the popular Korean online role playing game Lineage. The shellcode uses simple XOR decryption to obfuscate its functionality. The received SMIL sample clearly contained shellcode in the text tag attribute “system-screen-size”. The most popular player with SMIL support is Real Player. It is an XML based language for describing multimedia content such as interactive presentations for displaying in players without a requirement for a scripting language. SMIL, pronounced (smile), stands for Synchronized Multimedia Integration Language. Today we have received an interesting submission consisting of an SMIL file. Most of the exploits we see these days target the process space of Internet Explorer. If you want to re-authorize a blocked application, then you'll find re-authorization instructions in this knowledgebase article.Web and HTTP protocols are the most common vehicles for delivering exploits and web browsers are the most commonly targeted applications. (A single alert is the default setting.) Re-authorize a controlled application However, you can set your Application Control policy to send only a single alert per endpoint, so you will only be alerted once about any embedded applications. Note: A few of our controlled applications will not be removable because they are embedded within your operating system. Should this option not be available, double-click the uninstall file applicable to the specific application. Typically, applications can be removed using 'Add/Remove Programs'. Remove a controlled application using a specific application uninstallerĪt the time of installation, many applications have their own uninstall file that is placed in the same directory or program group. The 'Currently installed programs' list in the 'Add or Remove Programs' tool lists all of the Windows-compatible programs that have an uninstall program or feature.Ģ. To access the Add/Remove programs utility from the Windows Control Panel: Remove a controlled application using Add/Remove programs in Windows Control Panel remove the software to prevent future alertsġ.take no action, if you wish to continue blocking the application.If you've received an alert about a blocked application, you can choose to: System administrators choose applications that they wish to block. In the Application Control policy, applications are allowed by default.
