Product Description
Akamai Download Manager is a client software application that helps users download content easily, quickly, and reliably. It is available as an ActiveX component or Java applet and provides users the ability to pause, resume downloading at a later time, and automatically recover from dropped connections or system crashes.

Vulnerability Description
Two security vulnerabilities have been discovered in the ActiveX version of Akamai Download Manager. For successful exploitation, both vulnerabilities require the user to visit a malicious URL, triggering a stack-based buffer overflow that allows the attacker to execute arbitrary code within the context of the victim.

Vulnerability CVE-2007-1891 affects versions newer than 2.0.4.4 and older than 2.2.1.0. Vulnerability CVE-2007-1892 affects all versions prior to 2.2.1.0. Both are remediated by installing version 2.2.1.0 and upgrading to this version is recommended.

The Java version of Akamai Download Manager is not affected by either of these vulnerabilities.

These vulnerabilities exist only in the Download Manager client software and do not affect Akamai's services in any way.

Affected users can upgrade to the latest version of Akamai Download Manager by visiting the following web page:
