Kritiska sårbarheter i Windows

Sårbarhet Microsoft Windows

Microsoft har publicerat en säkerhetsbulletin gällande två sårbarheter i Windows. Fjärrexekvering av koder i Adobe Type Manager Library påverkar alla versioner av Windows och Windows Server som för närvarande stöds, men även Windows 7. [1]

En fjärrstyrd attack kan utnyttja dessa sårbarheter för att ta kontrollen över ett drabbat system. Sårbarheten i Adobe Type Manager Library (ADV200006) gör att systemet kan angripas genom att få användaren att öppna ett bedrägligt dokument eller förhandsvisa det i Windows Preview. [2]

Microsoft känner till problemet och har hittills bara sett begränsade attacker som utnyttjar sårbarheterna. Hittills finns ingen uppdatering som åtgärdar problemet utan denna väntas komma först i samband med nästa tisdagsuppdatering.
