Description:
Some vulnerabilities have been reported in EasyMail Objects, which can be exploited by malicious people to compromise a user's system.
1) A boundary error exists within the IMAP4 component of EasyMail Objects when processing arguments passed to the "Connect" method. This can be exploited to cause a stack-based buffer overflow via an overly long (greater than 500 bytes) string passed as the host name argument to the said method.
2) A boundary error exists within the SMPT component of EasyMail Objects when processing arguments passed to the "SubmitToExpress()" method. This can be exploited to cause a stack-based buffer overflow by passing an overly long argument to the affected method.
Vulnerability #2 is confirmed in emsmtp.dll version 6.0.1. Other versions may also be affected.
Successful exploitation allows execution of arbitrary code and requires that the user is e.g. tricked into visiting a malicious web site.
Solution:
Update to version 6.5.
