Skype < 1.4.0.84 Multiple Vulnerabilities (uncredentialed check)

critical Nessus Plugin ID 21209

Synopsis

Arbitrary code can be executed on the remote host.

Description

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. 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.

Solution

Upgrade to skype version 1.4.0.84 or later.
