Skype has issued an update for all Mac users, due to security concerns in Skype version 5.x for Mac which allows a malicious user to activate code on the victim’s computer.
A security researcher said today that he found a serious hole in the Mac version of Skype and proving that it was possible to send a specific message to a user of Skype and it would crash Skype and make it unusable.
Gordon Maddern, says he discovered the vulnerability about a month ago. He was chatting on Skype to a colleague about a payload when the payload executed in the colleague's Skype client accidentally.
He created a proof of concept that can be used in an attack but is not releasing details on it until Skype fixes the issue. He could not find the vulnerability in the Skype client for Windows and Linux, he said.
