There are fatal flaws in the three major browsers such as ambush IE

Experts warn that the newly discovered and uncorrected security flaws in the three browser software make the Web even more dangerous.

Last weekend, security researchers published detailed information on newly discovered defects in IE, Safari, and Firefox on the security mailing list.

Secunia stated on its website that flaws in Firefox and Safari can cause browser crashes, while flaws in IE can be used by hackers to control users' computers.

Secunia rated the risk of IE defects as "high risk". It stated that IE has been confirmed to have this defect, and other versions may also be affected. This flaw exists in the way IE handles HTML logos. By designing a malicious website, hackers can take advantage of this flaw.

Microsoft said in an email statement that Microsoft is investigating newly discovered defects and believes it is not as dangerous as Secunia claims. Microsoft said that our preliminary investigation revealed that this defect may cause the browser to close unexpectedly or not respond.

Symantec said that IE flaws can be used to run malicious code on defective PCs, but this has not been confirmed.

Secunia believes that Firefox and Safari defects are "not too critical." By designing a malicious website, these two flaws will cause the browser to crash.

Safari 2.0.3 has been confirmed to be defective, and other versions may also be affected. Firefox 1.5.0.2 has a defect, and earlier versions are also affected by the defect.

Since these defects have not been corrected, Secunia advises users not to visit untrusted websites to avoid being attacked.
