Date Discovered April 16, 2007
Description Akamai Download Manager is prone to multiple remote buffer-overflow vulnerabilities because the application fails to properly bounds-check user-supplied data before copying it into an insufficiently sized memory buffer.
Exploiting these issues allows remote attackers to execute arbitrary code in the context of applications using the affected ActiveX control and to compromise affected computers. Failed attempts will likely result in denial-of-service conditions.
These issues affect Akamai Download Manager prior to 18.104.22.168; other versions may also be affected.

Block external access at the network boundary, unless external parties require service. If global access isn't needed, filter access to the affected computer at the network boundary. Restricting access to only trusted computers and networks might greatly reduce the likelihood of successful exploits.
Run all software as a nonprivileged user with minimal access rights. Run all client applications with the least privileges required. This will reduce the chance of these issues being exploited.
Deploy network intrusion detection systems to monitor network traffic for malicious activity. Deploy NIDS to detect and block attacks and anomalous activity. Since the webserver may log such requests, review its logs regularly.
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.
Since a successful exploit of these issues allows malicious code to execute in web clients, consider disabling support for script code and active content within the client browser. Note that this mitigation tactic might adversely affect
legitimate websites that rely on the execution of browser-based script code.
The vendor has released version 126.96.36.199 to resolve these issues; please see the references for details.
