Säkerhetsbrist i Quicktime för Windows funnen

Häromdan publicerade GnuCitizen exempel på hur ett säkerhetshål i Quicktime kan utnyttjas till att att komma åt underliggande funktioner i webbläsaren Firefox. Och inte nog med det. Det visar sig även att det går att få tillgång till användarens operativsystem och program.

På bloggen visas ett "snällt" exempel på hur man kan starta miniräknaren i Windows genom att lägga in extrakod i Quicktime-koden. Man visar även hur man kan stänga av användarens dator. Vad för riktiga elakheter man kan hitta på med detta vill jag inte ens tänka på.

Så nu gäller det att se upp om man använder Windows och Quicktime. Rapporter visar på att även Opera och Internet Explorer kan vara sårbara för av denna säkerhetsbrist.

Ett sätt att skydda sig med Firefox verkar vara att installera tillägget NoScript. Det finns också tips om att använda ett alternativ till Quicktime som t ex Quicktime Lite.

Apple har vetat om detta säkerhetsproblem ett bra tag men inte gjort något åt det. Hoppas de börjar lyssna nu när man förstår vilken skada som det kan ställa till med hos webbsurfare.
