Subject: 
Vulnerability in Windows Common Control Library Could Allow Remote Code Execution (MS13-083)
Overview: 

A vulnerability has been discovered in Microsoft Windows Common control library. Windows common controls refers to a set of windows that an application uses in conjunction with another window to enable interaction with the user. This vulnerability could be exploited by a user opening a specially crafted Rich Text Format (RTF) file.  Successful exploitation could result in an attacker gaining the same privileges as the logged on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Failed exploit attempts will likely cause denial-of-service conditions.

Systems Affected: 
  • Windows XP Professional x64
  • Windows Server 2003
  • Windows Vista
  • Windows Server 2008
  • Windows 7

Description: 

A vulnerability has been discovered in Microsoft Windows Common control library. The vulnerability is caused when the DSA_InsertItem function in the Windows common control library improperly allocates memory for data structures. This vulnerability could be exploited by a user opening a specially crafted Rich Text Format (RTF) file. Successful exploitation could result in an attacker gaining the same privileges as the logged on user. Depending on the privileges associated with the user, an attacker could then install programs; view, change, or delete data; or create new accounts with full user rights. Failed exploit attempts will likely cause denial-of-service conditions.

Actions: 
  • Apply appropriate patches provided by Microsoft to vulnerable systems immediately after appropriate testing.
  • Run all software as a non-privileged user (one without administrative privileges) to diminish the effects of a successful attack.
  • Remind users not to download or open files from un-trusted websites
