How To Protect Your PC From Vulnerability | Microsoft Internet Explorer Uninitialized Memory CVE-2010-3328 Remote Code Execution Vulnerability

Risk: Microsoft Internet Explorer Uninitialized Memory CVE-2010-3328 Remote Code Execution Vulnerability

Risk Description: Microsoft Internet Explorer is prone to a remote code-execution vulnerability. Successful exploits will allow an attacker to run arbitrary code in the context of the user running the application. Failed attacks will cause denial-of-service conditions.
Risk Level: High
Date Discovered: October 12, 2010

Technologies Affected:
  • Avaya Aura Conferencing 6.0 Standard
  • Avaya Aura Conferencing Standard
  • Avaya CallPilot
  • Avaya Communication Server 1000 Telephony Manager
  • Avaya Meeting Exchange - Client Registration Server
  • Avaya Meeting Exchange - Recording Server
  • Avaya Meeting Exchange - Streaming Server
  • Avaya Meeting Exchange - Web Conferencing Server
  • Avaya Meeting Exchange - Webportal
  • Avaya Messaging Application Server
  • Avaya Messaging Application Server 4
  • Avaya Messaging Application Server 5
  • Avaya Messaging Application Server MM 1.1
  • Avaya Messaging Application Server MM 2.0
  • Avaya Messaging Application Server MM 3.0
  • Avaya Messaging Application Server MM 3.1
  • Microsoft Internet Explorer 6.0
  • Microsoft Internet Explorer 6.0 SP1
  • Microsoft Internet Explorer 6.0 SP2
  • Microsoft Internet Explorer 6.0 SP3
  • Microsoft Internet Explorer 7.0
  • Microsoft Internet Explorer 8
Run all software as a non privileged user with minimal access rights.
To reduce the impact of latent vulnerabilities, always run nonadministrative software as an unprivileged user with minimal access rights.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.
Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This includes but is not limited to requests that include NOP sleds and unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from successful exploits.

Do not accept or execute files from untrusted or unknown sources.
Exercise caution when handling files received from unfamiliar or suspicious sources.

Do not follow links provided by unknown or untrusted sources.
Web users should be cautious about following links to sites that are provided by unfamiliar or suspicious sources. Filtering HTML from emails may help remove a possible vector for transmitting malicious links to users.

Set web browser security to disable the execution of script code or active content.
Since a successful exploit of these issues requires malicious code to execute in web clients, consider disabling support for script code and active content within the client browser. 
This mitigation tactic might adversely affect legitimate websites that rely on the execution of browser-based script code.Implement multiple redundant layers of security.Various memory-protection schemes (such as nonexecutable and randomly mapped memory segments) may hinder an attacker's ability to exploit this vulnerability to execute arbitrary code.The vendor has released an advisory and updates. Please see the references for details.
