Sunbelt has just discovered a new IE zero day being used in the wild. The zero day exploit makes use of a vulnerability in the Vector Markup Language (VML) inside Internet Explorer to overflow a buffer and inject a shellcode.

I will update this as research on the said subject is still on going.

For those who don’t know, the vulnerable dll exploited by this zero day is VGX.DLL which is used by Internet Explorer for processing Virtual Markup Language.

Sunbelt has proposed turning off Javascripting to mitigate the exploit. Or you can just use an alternative browser like Firefox.

Microsoft has already been informed about the vulnerability, so far there isn’t a patch available yet, but give them time, it is a zero day after all.

This blog will be updated for the malware name given to the exploit code.

Update (Chachi, Wed, 20 Sep 2006 03:08:05 AM)

The exploit code will now be detected as EXPL_EXECOD.A and the executable files will be detected as TROJ_AGENT.FAC, TROJ_DELF.DBC, TROJ_DLOADER.EES.

These are now detected using Control Pattern 3.764.02
