IE Security Flaw

PCMag reported Microsoft late Thursday confirmed a security flaw in its dominant Internet Explorer browser could be potentially exploited by malicious hackers to take "take complete control of the affected system." The software giant released a security advisory acknowledging the vulnerability and recommended that IE users set Internet and local intranet security zone settings to "High" before running ActiveX controls in these zones.

ActiveX is dangerous, and I dont like to use it at all. In fact this is one good reason to use Firefox as a browser, since it does not support ActiveX.
All supported versions of Internet Explorer, including IE 6.0 in Windows XP SP 2 (Service Pack 2) are affected. Microsoft Corp.'s confirmation comes less than 24 hours after private security research firm SEC Consult published a working exploit to show that the bug could crash the browser or exploited to execute arbitrary code in the context of IE. Microsoft said it was not aware of any attacks attempting to use the reported vulnerability or customer impact and promised a patch would be made available once an investigation is completed. "A COM object, javaprxy.dll, when instantiated in Internet Explorer can cause Internet Explorer to unexpectedly exit. We are investigating a potentially exploitable condition," Microsoft said in the advisory.
