Microsoft Agent agentdpv.dll ActiveX Control Malformed URL Stack Buffer Overflow Vulnerability

Risk

High

Date Discovered

September 11, 2007

Description

Microsoft Agent (agentsvr.exe) is prone to a stack-based buffer-overflow vulnerability because the application fails to adequately bounds-check user-supplied data. Successfully exploiting this issue allows remote attackers to execute arbitrary code in the context of the currently logged-in user. Failed exploit attempts will likely result in denial-of-service conditions.

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.

Do not follow links provided by unknown or untrusted sources.

To reduce the likelihood of successful exploits, never visit sites of questionable integrity or follow links provided by unfamiliar or untrusted sources.

Set web browser security to disable the execution of script code or active content.

A successful exploit of this issue requires the execution of active content. To mitigate against this and other latent vulnerabilities, disable support for active content in the browser. Note that this mitigation tactic might adversely affect legitimate websites that rely on the execution of browser-based script code.

Do not open email messages from unknown or untrusted individuals.

Attackers could exploit this vulnerability through HTML email messages. Never accept any email from sources of questionable integrity.
Microsoft has released security advisory MS07-051 to address this issue in supported versions of affected applications. Please see the referenced advisory for more information.
