========================================================================
== Overview ==
During a security review of the safe-for-scripting EasyMail objects,
a stack overflow was discovered in the connect method of EasyMail IMAP4
(Object ClassID {703B353E-FA2E-4072-8DDF-F70AAC7E527E}).
This advisory is also available online at
http://www.security-assessment.com/files/advisories/easymail_advisory.pdf
== Exploitation ==
When the object is initialized and the Connect method is called, a stack
overflow is possible when a large (500+ characters) host name is specified.
Once arbitrary data has been written to the stack, it is possible to
overflow the structured exception handler and gain command execution.
== Solutions ==
Security-Assessment.com has been in contact with Quiksoft and a
new version of the software has been released to address the discovered
vulnerability.
Security-Assessment.com urges EasyMail users to upgrade to the latest
version
which is available at
