RealNetworks has released a security patch for its media player to stop hackers running their own code on users’ machines via a buffer overflow attack.
The flaw has been classed as “highly critical” by security research company Secunia, and affects most recent versions of RealNetworks’ Real Player software for Windows and the Mac.
RealNetworks said it hadn’t so far received any reports of the security flaw leading to any attacks on users’ machines.
The European Commission has ordered Microsoft to launch a European version of Windows XP without the Windows Media Player console.
The move is designed to give companies like RealNetworks a better chance of carving out a decent portion of the media player market, and is part of last year’s competition settlement with Microsoft.
Microsoft itself has recently released patches to close security holes in Windows Media Player.
