DESCRIPTION:
Secunia Research has discovered some vulnerabilities in GIGABYTE
Dldrv2 ActiveX Control, which can be exploited by malicious people to
compromise a user's system.

1) The unsafe method "dl()" allows automatically downloading and
executing an arbitrary file.

2) Combined usage of the unsafe methods "SetDLInfo()" and "Bdl()"
allows automatically downloading an arbitrary file to an arbitrary
location on the user's system.

3) Missing input validation of the "item" argument passed to the
"SetDLInfo()" method can be exploited via array-indexing errors to
overwrite memory and execute arbirtary code.

The vulnerabilities are confirmed in version 1.4.206.11. Other
versions may also be affected.

SOLUTION:
Set the kill-bit for the affected ActiveX control.

PROVIDED AND/OR DISCOVERED BY:
Carsten Eiram, Secunia Research.
