software. 

The remote version of this software is vulnerable to a heap overflow

flaw by sending a specially crafted network packet to UDP or TCP ports
Skype is listening on. A successful exploitation of this flaw will 
result in code execution on the remote host. 

In addition, Skype has been reported to contain overflows in the
handling of VCards and callto/skype URLs. However, Nessus has not
checked for them.");
