TITLE:
Juniper Networks IVE ActiveX Control Buffer Overflow

SECUNIA ADVISORY ID:
SA19842

VERIFY ADVISORY:
http://secunia.com/advisories/19842/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

OPERATING SYSTEM:
Juniper IVE OS Software 4.x
http://secunia.com/product/6645/
Juniper IVE OS Software 5.x
http://secunia.com/product/6644/

DESCRIPTION:
eEye Digital Security has reported a vulnerability in Juniper IVE OS,
which can be exploited by malicious people to compromise a user's
system.

The vulnerability is caused due to a boundary error within the
"JuniperSetupDLL.dll" of the SSL-VPN client IVE ActiveX control. This
can be exploited to cause a stack-based buffer overflow when the
control is instantiated with an overly long "ProductName" parameter.

Successful exploitation allows arbitrary code execution, but requires
that the user is e.g. tricked into visiting a malicious web site.

The vulnerability has been reported in versions 1.x through 5.x.

SOLUTION:
Update to IVE software version 5.3r2.1, 5.2r4.1, 5.1r8, 5.0r6.1, or
4.2r8.1.

PROVIDED AND/OR DISCOVERED BY:
