IE6 and IE7 vulnerable to latest flaw; IE8 immune

URL: http://feeds.arstechnica.com/~r/arstechnica/index/~3/tFARTMEec7s/ie6-and-ie7-vulnerable-to-latest-flaw-ie8-immune.ars


Microsoft has issued Security Advisory 977981 in regard to public reports of a vulnerability that exists as an invalid pointer reference of Internet Explorer. Under certain conditions, it is possible for a CSS/Style object to be accessed after the object is deleted, and thus, if Internet Explorer attempts to access the supposedly freed object, it can end up running attacker-supplied code. IE6 SP1 on Windows 2000 SP4, as well as IE6 and IE7 on supported editions of Windows XP, Windows Server 2003, Windows Vista, and Windows Server 2008 are affected. Microsoft notes that IE 5.01 SP4 and IE8 on all supported versions of Windows are not affected, but of course IE6 and IE7 still account for over 40 percent of the browser market.

Lack of cross-platform support in Silverlight 4 explained

URL: http://feeds.arstechnica.com/~r/arstechnica/index/~3/AyiVV8jjAvY/lack-of-cross-platform-support-in-silverlight-4-explained.ars


As with any new release, in Silverlight 4, Microsoft has made some changes that developers like and others do not. There are too many to list of the former, and just a handful of the latter, but one of them is quite serious: cross-platform support has become less of a priority, as The Register reports. For example, the HTML control in Silverlight 4 uses components from Internet Explorer on Windows and from Safari on the Mac. How bad can that be? Well, considering the same content is likely to render differently between the two browsers, this slightly defeats the purpose of using Silverlight to write one application that works on both platforms. That's the lesser evil, though.

Microsoft assume responsabilidade por violação da GPL

URL: http://feedproxy.google.com/~r/NoticiasLinux/~3/6338y5Jl7gs/nl1258325846.html


A Microsoft publicará o código da ferramenta WUDT, utilizada para gravar o sistema operacional Windows 7, baixado da internet, em um DVD ou em um pendrive. Liberará tanto o código fonte como os arquivos binários nesta semana. O incidente se deveu a um incorreto processo de revisão do código da ferramenta, que havia sido subcontratada a uma empresa terceirizada, mas que foi de fato baseado no projeto ImageMaster, licenciado sob GPLv2.

Microsoft Disconnects Modded Xbox Users

S-4'N3 writes "The BBC reports that Microsoft has disconnected approximately 600,000 Xbox users from Xbox Live because the devices they are using have been modified, either with software or with new chips, to play pirated games. 'Microsoft confirmed that it had banned a "small percentage" of the 20 million Xbox Live users worldwide. Microsoft said that modifying an Xbox 360 console 'violates' the service's 'terms of use' and would result in a player being disconnected.'"

Microsoft Plugs "Drive-By" and 14 Other Holes

CWmike writes "Microsoft today patched 15 vulnerabilities in Windows, Windows Server, Excel, and Word, including one that will probably be exploited quickly by hackers. None affects Windows 7. Of today's 15 bugs, Microsoft tagged three 'critical' and the remaining 12 'important.' Experts agreed that users should focus on MS09-065 first and foremost. That update, which was ranked critical, affects all still-supported editions of Windows except Windows 7 and its server sibling, Windows Server 2008 R2. 'The Windows kernel vulnerability is going to take the cake,' said Andrew Storms, director of security operations at nCircle Network Security. 'The attack vector can be driven through Internet Explorer, and this is one of those instances where the user won't be notified or prompted. This is absolutely a drive-by attack scenario.' Richie Lai, the director of vulnerability research at security company Qualys, agreed. 'Anyone running IE [Internet Explorer] is at risk here, even though the flaw is not in the browser, but in the Win32k kernel mode driver.'"

Microsoft violates GPL

URL: http://linuxtoday.com/news_story.php3?ltsn=2009-11-11-002-35-OP-LL-DV


Cyber Cynic: "Microsoft has long ripped off free software. The canonical case is that Microsoft's first version of the fundamental TCP/IP network stack, which underlies the Internet and almost all business networking, was swiped from the BSD-licensed Unixes. Years later, it seems Microsoft still can't resist stealing from open-source software."

Are Microsoft to blame for "hidden" malware costs and will Windows 7 make any difference?

URL: http://www.freesoftwaremagazine.com/columns/microsoft_hidden_malware_costs_windows_7


A couple of stories have hit the headlines this year concerning the huge cost that some UK Local Governments incurred when dealing with malware attack on their Windows machines. If you missed them, Manchester City Council had a single USB infected with the infamous Conficker worm and it cost them — brace yourself — £1.5m ($2.4m) of which £1.2m (US$1.9m) was spent on IT, of which a staggering £600,000 (US$980k) went on consultancy fees including money to Microsoft. A while later, Ealing Borough Council were hit with a cost of £500000 (about US$ 800k) when they were also hit by a single USB stick containing conficker. Some in the industry tweeted and blogged this as being a “hidden cost of using Microsoft Windows”. In the ensuing discussion, many pointed out that the high cost was really due to the lack of a proper patching and disaster recovery policy at the council. So which is right? Is dealing with malware a hidden cost of using Windows or of a poor IT strategy?
