Skype 7.2.x / 7.35.x / 7.36.x < 7.37 MSFTEDIT.DLL RDP Session Clipboard Handling RCE

high Nessus Plugin ID 101084

Language:

Synopsis

An instant messaging application installed on the remote Windows host is affected by a remote code execution vulnerability.

Description

The version of Skype installed on the remote Windows host is 7.2.x, 7.35.x, or 7.36.x prior to 7.37. It is, therefore, affected by a stack buffer overflow condition in MSFTEDIT.DLL due to improper validation of images taken from the RDP session clipboard and which are pasted into the Skype message field when doing screen captures from an RDP client. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or potentially the execution of arbitrary code.

Solution

Upgrade to Skype version 7.37 or later.
