Microsoft Windows Media Player SSPL File Sample Rate Remote Code-Execution Vulnerability

Risk

High

Date Discovered

September 9, 2008

Description

Microsoft Windows Media Player is prone to a remote code-execution vulnerability. An attacker can exploit this issue to execute arbitrary code with the privileges of the user running the affected application. Failed exploit attempts will result in a denial-of-service condition. NOTE: Supported editions of Windows Server 2008 are not affected if installed using the Server Core installation option.

Technologies Affected

  • HP Storage Management Appliance 2.1
  • HP Storage Management Appliance I
  • HP Storage Management Appliance II
  • HP Storage Management Appliance III
  • Microsoft Windows Media Player 11
  • Nortel Networks ENSM - Enterprise NMS 10.4
  • Nortel Networks ENSM - Enterprise NMS 10.5
  • Nortel Networks ENSM- Enterprise NMS

Recommendations

Run all software as a nonprivileged 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.

To reduce the likelihood of successful attacks never handle or open files from unknown sources.

Implement multiple redundant layers of security.

Memory-protection schemes (such as nonexecutable stack and heap configurations and randomly mapped memory segments) will complicate exploits of memory-corruption vulnerabilities.
The vendor has released updates and an advisory. Please see the references for more information.
