Mozilla issues security updates

The Mozilla Foundation has issued "critical" security updates to vulnerabilities discovered in the Firefox browser, Thunderbird e-mail client and SeaMonkey application suite.

Flaws were found in versions of the open-source software prior to both Firefox 2.0.0.1 and Firefox 1.5.0.9, as well as prior to Thunderbird 1.5.0.9 and SeaMonkey 1.0.7, Mozilla said Tuesday.

The vulnerabilities could potentially be exploited to conduct cross-site scripting attacks, to let malicious attackers launch a remote execution of code on users' computers, and to expose sensitive information, according to an advisory from security company Secunia.

While Mozilla labeled the updates "critical," Secunia rated them "highly critical."

Mozilla advised people to forgo enabling JavaScript in Thunderbird and the mail portions of its Internet application suite SeaMonkey. People are also advised to download SeaMonkey 1.0.7, which is undergoing its final paces of testing.

"Some of these (flaws) were crashes that showed evidence of memory corruption, and we presume that at least some of these could be exploited to run arbitrary code with enough effort," according to one of six-related "critical" Mozilla security advisories issued Tuesday.

Last month, Mozilla also issued "critical" security updates for Firefox, Thunderbird and SeaMonkey. Like the new flaws, the earlier ones involved the potential for malicious attackers to take hold of users' systems.

A bit misleading, don't you think

Okay, I've come to not expect "fair and balanced"(TM) reporting from c|Net but come on.

"While Mozilla labeled the updates "critical," Secunia rated them "highly critical.""

Of course Mozilla ONLY labeled the updates "critical", Mozilla's impact key ONLY goes up to critical.

This is just poor journalism.

Not really much of an issue...

Since most FF users use NoScript. Most pages I visit never run one line of JavaScript period. Cross Site scripting never happens until I implicitly trust both sites.

Opera...

... is the most secured. Compare:

Opera 9 - 2 patched
http://secunia.com/product/10615/?task=advisories

FF 2 - 1 patched; 1 unpatched
http://secunia.com/product/12434/?task=advisories

IE 7 - 3 unpatched
http://secunia.com/product/12366/?task=advisories

Safari 2 - 2 patched; 3 unpatched

Hmmm...

A prediction: Google's motto is 'Do no Evil' yet their floatation has made them less warm and fuzzy and more corporate. As Firefox matures as a business there will be the temptation to 'make money' (even though they make millions of dollars through search partnerships already!), will bring Firefox into the corporate lime light and the tecnical self appointed elite will turn on them. They will become a traget just like Microsoft - for the ethical, and not-so-ethical hackers looking to 'kick' the corproate man for turning against the geekorati. Or, in the case of 'security' companies, to make a name for themselves.

Watch this space...

of this constant bickering about who's right and who's wrong or which is better and which is worse.

Their is no truth to be found. It's all a one sided story. The only real difference between any of us is which side we choose to believe.

Look, you sack of ****, here are just two here. I'll leave it to you with your third grade education to find the rest. Ya know, why don't you do us all a favor and leave this board, as it's the low rent wannabees who have no understanding of how little they know, that ruin it for the rest of us?
