Apple's Safari web browser has come under scrutiny after the discovery of a critical 'zero-day' bug in the Windows version of the application.
The bug, discovered by Danish IT security company Secunia and the US Computer Emergency Readiness Team (US-CERT), exploits a vulnerability in the way Safari works on Windows operating systems that could lead to remote code execution attacks on computers.
Will Dormann of US-CERT wrote on the organisation's web page: “Exploit code for this vulnerability is publicly available. We have confirmed Apple Safari 4.0.5 on the Windows platform to be vulnerable. Other versions may also be affected.”
US-CERT suggested that users of affected browsers should access the browser using non-administrator accounts to stop the malicious code being given permission to run.
Users were also advised not to follow random links on unconfirmed web pages.
