This signature detects an attempt to exploit a remote buffer overflow vulnerability in Quiksoft Easymail application.
Quiksoft EasyMail is an application that provides email sending/receiving for ActiveX applications.
EasyMail is prone to a buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied data. The vulnerability affects the 'AddAttachment()' method of the ActiveX control identified by CLSID: 68AC0D5F-0424-11D5-822F-00C04F6BA8D9.
An attacker can exploit this issue by enticing an unsuspecting user to view a malicious HTML page.
Successful exploits allow remote attackers to execute arbitrary code in the context of the application using the ActiveX control (typically Internet Explorer). Failed exploit attempts will likely result in denial-of-service conditions.
EasyMail 6 is vulnerable; other versions may also be affected.
