The remote host may be tricked into running an executable file
The version of Skype installed on the remote host is vulnerable to a flaw wherein specially formatted 'file://' URI will allow the download and execution of executable files. An attacker, exploiting this flaw, would need to be able to coerce a user into browsing a malicious URI. Successful exploitation would result in the attacker executing arbitrary code.
Upgrade to Skype release 22.214.171.124.
