Microsoft - Now there is a jpg security issue

Postby Glen on Fri Sep 17, 2004 6:53 am

Microsoft has announced there is a security issue with Windows, Office and some third party programs dealing with jpgs. I am assuming most here have a jpg or two on their pc, might be worth heading over to windowsupdate at microsoft to see if they need an update (yes, this is on top of sp2)

Hi Birddog, Photokina would have been a great option! Just working a little bit too hard. Only time I picked up a camera this week was to show a client why he should get a DSLR instead of a point and shoot and took two shots of my drink bottle to show him depth of field! What is life coming to? :D

"...Windows XP Service Pack 2, which is still being distributed to many customers' computers, is not vulnerable to the flaw."

Yeah, but try playing any game on Linux. No API support, even mainstream vid drivers are rare. ;)

Also an office fix involved

Postby Glen on Fri Sep 17, 2004 9:50 am

Onyx, probably not a problem on your travelling laptop, but there is also a fix for Microsoft Office and then a third scan for third party software which may be vulnerable. All on the microsoft website.

Well, currently it's just a vulnerability - no one's exploited it yet (touch wood).

Thank god Onyx, can you imagine not being able to open a jpg without worrying? I can imagine it must be possible because in a different life when I used to spend 6 months a year travelling, my business partner and I had a program which would hide information inside jpgs. Not excel files or anything just ascii but from memory about 500-600 characters inside a jpg. Would look like a jpg to anyone but after going through this program the message would come out. Don't think it had any great encryption, really just no one would take a second glance at a jpg.

Virus

Postby Killakoala on Fri Sep 17, 2004 9:19 pm

It would be very challenging for a programmer/virus writer to write malicious code in a JPG anyway. It's not executable. I'd like to hear Microbloats uptake on WHY they think it could be a problem.

Steve,

I could envisage a situation, when you're looking at an image displayed in IE, and where that image might contain some scripting commands that might be malicious.
