This
new JPEG vulnerability in Windows has me scared. I'm generally
pretty virus-immune: I don't read email on Windows, I've got Norton
AntiVirus on my Windows box, and I don't generally run unknown
programs. But I do look at a lot of JPEGs. And now there's at least
one JPEG virus in the
wild.
Windows Update is one of the great unheralded Microsoft technologies. It really works. Well, mostly. I downloaded the various JPEG fixes from them and thought I was safe until I ran GDI Scan, a deep scan tool that tries to find vulnerable versions of the DLL. And it found a vulnerable version, C:\WINDOWS\system32\gdiplus.dll. Now what do I do? I don't know where to get an update. Do I have to install Service Pack 2? Does that even fix the problem? I'm a software professional and I'm confused. What does the other 99% of the world do? At least Norton Antivirus blocks it. I downloaded a virus sample and Norton AntiVirus dedicted it as Roxe and wouldn't let me copy it to my Windows box.
Update 2004-10-01. The Washington Post has
a
story on this. And thanks to
Jon
Udell I learned about
this
forum post with instructions on how to run GDI Scan and how to
manually patch the broken DLL.
