Heartbleed bug
Вече всеки сигурно е чул за бъга в openssl наречен „Heartbleed bug“ – или пробив в SSL сигурността, която позволява на „хакера“ да вижда потребителските имена или паролите в чист текст, които иначе трябва да са криптирани в реално време.
През сайта http://filippo.io/Heartbleed/ може да се провери сигурността на даден сайт, изпозващ SSL сертификат, дали е засегнат от Heartbleed bug.
Ето какво се пише по темата във linux-bg.org :
В реализацията на OpenSSL версии 1.0.1 и 1.0.2-beta, включително 1.0.1f и 1.0.2-beta1, е открит проблем в сигурността който позволява на отдалечен потребител да прочете информация от оперативната памет на порции от 64К. Ако ползвате някоя от засегнатите версии се препоръчва да обновите възможно най-скоро до нова версия.
Проблемът е от повече от две години и е открит наскоро от специалисти по сигурността в Google.
Ето и една интересна таблица от mashable.com, която показва някой от известните уеб сайтове и дали са уязвими от този бъг:

Тъй като windows 8.1 взе да ми харесва много – бърз е и доста стабилен, реших да го сложа на десктоп машините които имам – в къщи и в нашите.
Привет,
