Three New Microsoft Bulletins
Jimmy M writes "Microsoft has released three security bulletins for January, which correct vulnerabilities in the handling of Icon and Cursor files, Indexing Services, and HTML Help. Bulletin MS05-001 (HTML Help) is the Extremely Critical vulnerability (Demonstration) that Secunia warned about last week - nice to see a quick move from MS. All updates are available from Windows Update."
The extremely critical exploit was listed on 2004-10-20! It took nearly three months to fix.
It should be noted that those with XP SP2 are only affected by MS005-01.

Microsoft Security Bulletin MS05-001 addresses the cross-domain vulerability with their HTML Help Active-X control. Microsoft mentions that it's "newly" discovered, but see the proof-of-concept at Security Focus--posted into BugTraq almost a month ago.
Incidentally, if you're one of those rare Windows users running IE in restricted (ESC) mode, your vulnerability is mitigated... suprise, suprise.
Did anyone else think that sounded like something out of one of the Lemony Snicket books?

It would also seem microsoft released "Malicious Software Removal Tool" on WindowsUpdate
It finds and fixes some common worms.. They plan on releasing a new version every second Tuesday of each month, and each new version will continue to clean worms from the previous versions.
Wonder what the antivirus companies think about this

Nice to know that all software is flawed, because it is made by flawed humans. Nothing is inherently better than the other, Linux or Windows. Don't forget yesterday's Linux security article. Just a friendly reminder before the regularly scheduled Microsoft-bashing...now have at it. :)
Yes nice and quick. Only took nearly three months!
Release Date: 2004-10-20

I'll probably be modded down for this...
"Bulletin MS05-001 (HTML Help) is the Extremely Critical vulnerability (Demonstration) that Secunia warned about last week - nice to see a quick move from MS."
Michael, are you kidding me? Read the advisory and the discussion from last week. Microsoft was notified at the beginning of October and has only now gotten around to fixing it.
...nice to see a quick move from MS.
My thoughts exactly. The focus for many on the anti-MS side of things is not the fact that there are vulnerabilities, it's how they are handled. Grats to MS for tackling this one.

Looks like they're finally getting tired of the most common viruses running rampant.

nice to see a quick move from MS
MS does something good. How many people will still insult this statement just outta spite for MS? How many will reply to me saying I'm out of my mind?
I'm already a comment wading in the anti-MS sludge. Will people see MS is trying to do the right thing?
Good quote, too many chars. Seriously, the slashdot 120 char limit sucks!
the handling of Icon and Cursor files
Heh, now only notepad hasnt had a vulnerability yet.
Nevermind that did too.
Bad policy: Accept all, but let people turn things off.
Worse policy: Accept all, but let people turn fewer things off depending on four arbitrary "zones" something falls into.
Worst policy: Make sure the "zones" in question have nothing to do with TCP/IP, netmasks, DNS, or any other networking concept, but make sure they're supported by a proprietary application you've embedded deeply into the OS to facilitate an embrace/extend/extinguish business model.
Then act all surprised when everyone ends up running at least one of these "zones" (namely the "local" one, which ought to be the most trustworthy) with their proverbial pants down, thereby creating a guaranteed 100% available target for Worm/Spyware/Virus authors.
Can someone please find the creature responsible for "Internet Zones" and beat him to death with a large wooden mallet?
I don't normally stoop to Microsoft Bashing, but security vulnerabilities in icons and cursors?!?!?
Wanted: witty unique signature. Must be willing to relocate.
which correct vulnerabilities in the handling of Icon and Cursor files
Seriously now. How the hell did they work that one in? Security flaws in Icon files.
Amazing.
I personnally like the "malicious software removal tool" windows update is in the process of installing... along with the other security patch of course :)
I dont think he even uses windows.
Either way, windowsupdate was slashdotted and that's all that matters.
Wonder what the antivirus companies think about this
Probably very little...
McAfee already publishes a similar tool called Stinger which is periodically updated to cover new worms.
Have fun with your Yugo chump, nothing is better, Yugo or Lamborghini, so I'll take the Lamborghini, you go prove the concept.
Fixes available via Windows Media Player ...
I find this part of the security bulletin especially interesting:
"Windows 2000 is not affected by this vulnerability. However the additional security-related change does affect Windows 2000 and we recommend customers install this update."
The old adage usually goes "if it ain't broke, don't fix it". Why would they ask people to patch something that isn't broken? Does this indicate that they expect to find a similar flaw in the indexing service on Win2K?
But what does it say when it finds Alexa?
First, Secunia released the advisory for Windows security update 890175 (MS05-001) back in 2004-10-20. Secunia linked to a workaround for the flaw 8 days after this, that was posted by Microsoft. Secunia increased the severity rating in 2005-01-07, and 4 days later, Microsoft has now posted an actual fix.
Now, the story, unfortunately for Windows users, and fortunately for e.g. open source evangelists, it seems like there is some things to be aware of if needing to uninstall the fix, for example due to possible problems caused by this fix, which are mentioned here, under the "Known Issues" heading.
In other words, we're talking about one issue that may appear as a direct consequence of installing this (my first link) and another one if you then decide to uninstall this fix (my second link).
Of course, if you aren't subject to the first problem, you don't need to do a thing and you are indeed living in the environment Microsoft was crossing their fingers for that you would be in.
Beware: In C++, your friends can see your privates!
I had to deal with an Indexing Service security issue last week.
Seems the guy that handles the website content got upset when Indexer, well, Indexed the website, finding some content that was a little more sensitive then he wanted out there.
(It's what happens when your contractor migrates your data, then neglects to remove the temp data when the migration is done, I guess.)
"Draco dormiens nunquam titillandus."
Why, exactly, should I have to reboot my machine after installing a scanning tool?
MS Anti-Spyware? Doesn't that classify as an oxymoron?
At least it's not in the kernel...
...and these were announced on one day! Notice Slashdot is silent.
I've seen plenty of weird things in Linux distros, like privilege escalation in MPlayer. MPlayer, a video player! People really need to start paying attention to LinuxSecurity and witness all the monthly vulnerabilities for their distros. They rarely get mentioned on Slashdot (for whatever reason).
Random sampling from Gentoo's advisory list:
Gentoo: HylaFAX hfaxd unauthorized login vulnerability
Date: Tuesday, 11 January 2005
HylaFAX is subject to a vulnerability in its username matching code, potentially allowing remote users to bypass access control lists.
Gentoo: o3read Buffer overflow during file conversion
Date: Tuesday, 11 January 2005
A buffer overflow in o3read allows an attacker to execute arbitrary code by way of a specially crafted XML file.
Gentoo: imlib2 Buffer overflows in image decoding
Date: Tuesday, 11 January 2005
Multiple overflows have been found in the imlib2 library image decoding routines, potentially allowing the execution of arbitrary code.
Gentoo: Kpdf, Koffice More vulnerabilities in included Xpdf
Date: Tuesday, 11 January 2005
KPdf and KOffice both include vulnerable Xpdf code to handle PDF files, making them vulnerable to the execution of arbitrary code if a user is enticed to view a malicious PDF file.
vulnerabilities in the handling of Icon and Cursor files
Wow! As tough to beat as that is, I think Apple still wins the day.
Tough call.

Can anyone think of any replacements for MS HTML Help? Something I can use to read the MSDN docs that isn't slow as hell or full of bugs?
Thanks in advance...

Perhaps the same way as the widely-used and open source libpng library had a number of vulnerabilities last year? (ref 1, ref 2)
Or the same sort or way the Mozilla XBM vulnerability arose? (ref)
This isn't a new thing, and it's not unique to Microsoft, either.
If you disagree, post your argument. (-1, Overrated) isn't your personal censorship tool for views you don't like.
Maybe now they'll find some time to fix the highly critical flaw in IE 5 & 6 that was reported on 8/14/2003 that allows a malicious web site to execute arbitrary code on the hapless victims machine. Timeliness is next to godliness!
--- What?
I ran windows update, and got the full package including the Malicious Software Removal Tool.
During the update, the Steam icon on my desktop flickered.
Sure enough, steam.exe appears to have been removed, presumably by the aforementioned removal tool.
Am I the only one out there who's had this happen? (in which case, I'm hallucinationg, and all will be ok by morning)
Political language
I think all of us should pause for a moment and thank the Gods for XP SP2's security center's automatic download and installation over BITS feature. At least know we know that these updates stand slightly more chance than a snowball in hell of being installed on a friend/neighbours/relatives machine that's been seen to by helpful slashdotters over christmas.
SP2, well yeah, hardly perfect I know. But you've got to love the fact that (l)users are now forefully made aware of possible(read inevitable) security problems as they arise.
May the Maths Be with you!
Many websites include a favicon.ico file in the root directory of the site. This icon is used in favorites to display the site's logo, etc.
Now, without knowing too much about this vulnerability, it seems possible (likely?) that any Windows app that displays icons would be at risk since the rendering of icons is handled by the OS.
In theory, Firefox would be as much at risk as IE -- both display favorite icons. And neither has a way to block the display of these icons.
(The CAN notice is "under review", so I can't be much more specific than that.)

Let's hope it's not a truly malicious software removal tool.
Please correct me if I got my facts wrong.
Hmmm, word grouping makes a difference!
Given reports that the Malicious Software Removal Tool has identified benign programs (e.g. VNC) as infected, maybe BOTH of the following groupings apply!
Is this a:
i.e. (Malicious Software) (Removal Tool)
OR
i.e. (Malicious) (Software Removal Tool)
Freudian slip?
Right after I switch my entire environment from linux to windows due to the amazing overwhelmingly dangerous linux kernel exploit from a few days ago and the huge number of linux security issues that were said to be listed this year... this happens. Now my Win2003 server uptimes will get all jacked up.. and they just booted for the first time 2 days ago. Now I'm going to have to switch to OS/1337 in order to preserve my sys admin ego flames.
Don't use windows. Don't use linux. They both suck. OS/1337 has not once had a single crack or exploit discovered. Plus.. it has never crashed. Not once. OS/1337 will rock your world.
An attacker could entice a user to open a specially-crafted PDF file, potentially resulting in the execution of arbitrary code with the rights of the user running the affected utility.
That is not a linux problem. That is an Xpdf problem. Xpdf is letting the maker of a PDF file gain the rights that the Xpdf program normally has. Now, if this exploit allowed the user to gain root access (assuming the current user is not root) there would be a tad more going on as Xpdf should never have root access.
Now this isn't to say linux is perfect, but saying that every linux application security bug is the fault of linux isn't true either. However, this really comes down to the design differences between linux and windows. Running linux as root all the time can be just as dangerous as windows.
It is also a problem of monolithic vs. modular programming. Having IE, your window to the internet, being so deeply imbedded into your OS is only asking for problems.
Semi-offtopic, but could anyone recommend a good RSS to follow to alert about vulnerabilities? It doesn't even have to be MS or Linux specific. I tried following CERT, but theirs is behind (they don't even have this posted).
Thanks,
Daniel
This isn't a Windows flaw, it's a Visual Studio flaw.
Hey, you guys like to say exploits in Linux widgets like XPdf aren't Linux flaws, so it cuts both ways. All bad things seem to be lumped under the heading "Windows," but let a flawed RPM come to light and it's a "that's not Linux" buffet for all.
Make the same standard apply to both or not at all. Double standards are lies masquerading as virtue.
In the end they will lay their freedom at our feet and say to us, Make us your slaves, but feed us. - Fyodor Dostoyevsky
Yes, some apps don't run nice when you're not admin, but you don't have to run as admin. Thus any IE exploits would only be running under your credentials, not Localsystem, and thus the risk is the same as xpdf.
Nope... the point is that earlier MS used to take its own good time to fix any IE bugs. It's much faster (at least for IE) now as FF is gaining a bit of momentum.
This plugin is part of Visual Studio version 6. However, since the plugin is digitally signed by Microsoft, it may be silently installed through Internet Explorer by any website. The user doesnt have to have Visual Studio installed, they only have to visit a page using the control. And like it states, the control is digitally signed, so its supposed to be safe, right? "Always allow content from Microsoft.com" is one of the funniest things Ive ever seen on computers.
The patches they announce do.
Honey, I shrunk the Cygwin
Hey, you guys like to say exploits in Linux widgets like XPdf aren't Linux flaws, so it cuts both ways.
Bullshit. /. has 1000's of readers. Some refer to Linux-the-OS, others refer to Linux-the-kernel. No double-standard, just a variety of opinions. As you'd expect on a discussion site that isn't a lying marketing tool.
