TITLE:
PC-cillin Internet Security Insecure Default Directory Permissions

SECUNIA ADVISORY ID:
SA19282

VERIFY ADVISORY:
http://secunia.com/advisories/19282/

CRITICAL:
Less critical

IMPACT:
Manipulation of data, Privilege escalation

WHERE:
Local system

SOFTWARE:
Trend Micro PC-cillin Internet Security 2006 / 14.x
http://secunia.com/product/8828/

DESCRIPTION:
Dominique GREGOIRE has discovered a security issue in PC-cillin
Internet Security, which can be exploited by malicious, local users
to gain escalated privileges.

The problem is that insecure default permissions are set on the
application directory (grants "Everyone" group "Full Control" on the
"Internet Security 14" directory or grants "Users" group "Full
Control" on the "Internet Security 2006" directory depending on the
installed version). This can be exploited to remove, manipulate, and
replace any of the application's files.

The security issue has been confirmed in versions 14.00.1485 and 2006
(14.10.0.1023). Other versions may also be affected.

SOLUTION:
Grant only trusted users access to affected systems.

Set proper permissions on the "Internet Security 14" / "Internet
Security 2006" directory and all child objects. This may affect the
functionality.

Microsoft Internet Explorer "createTextRange()" Code Executi

TITLE:
Microsoft Internet Explorer "createTextRange()" Code Execution

SECUNIA ADVISORY ID:
SA18680

VERIFY ADVISORY:
http://secunia.com/advisories/18680/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
From remote

SOFTWARE:
Microsoft Internet Explorer 6.x
http://secunia.com/product/11/

DESCRIPTION:
Secunia Research has discovered a vulnerability in Microsoft Internet
Explorer, which can be exploited by malicious people to compromise a
user's system.

The vulnerability is caused due to an error in the processing of the
"createTextRange()" method call applied on a radio button control.
This can be exploited by e.g. a malicious web site to corrupt memory
in a way, which allows the program flow to be redirected to the
heap.

Successful exploitation allows execution of arbitrary code.

The vulnerability has been confirmed on a fully patched system with
Internet Explorer 6.0 and Microsoft Windows XP SP2. The vulnerability
has also been confirmed in Internet Explorer 7 Beta 2 Preview. Other
versions may also be affected.

SOLUTION:
Do not visit untrusted web sites.

NOTE: The vendor is currently working on a patch.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
