Skype < Multiple Remote Overflows (credentialed check)

Critical Nessus Plugin ID 20090


Arbitrary code can be executed on the remote host.


The remote host is running Skype, a peer-to-peer, voice-over-IP software.

The remote version of this software is vulnerable to a heap overflow in the handling of its data structures. An attacker can exploit this flaw by sending a specially crafted network packet to UDP or TCP ports Skype is listening on.

Successful exploitation of this issue may result in a crash of the Skype user client or code execution on the remote host.


Upgrade to skype version or later.
