Microsoft frigiver nye Windows 10 opdateringer

Microsoft frigav i dag et nyt sæt kumulative opdateringer til Windows 10 pc'er, der kører opdateringen fra maj 2019 og tidligere. Med frigivelse to uger efter denne måneds opdateringer af "Patch Tuesday", fokuserer de nyeste udgivelser på at løse et enkelt sikkerhedsproblem med Internet Explorer.

Rettelsen til Internet Explorer er det eneste, der er inkluderet i disse nye opdateringer. Som det bemærkes i Microsofts udgivelsesnotater, fokuserer opdateringerne specifikt på at korrigere en sårbarhed med eksekvering af fjernkode i alle versioner af Windows 10 version 1511.

Her er en beskrivelse af problemet fra Microsofts sikkerhedsopdateringsvejledning:

“A remote code execution vulnerability exists in the way that the scripting engine handles objects in memory in Internet Explorer. The vulnerability could corrupt memory in such a way that an attacker could execute arbitrary code in the context of the current user. An attacker who successfully exploited the vulnerability could gain the same user rights as the current user. If the current user is logged on with administrative user rights, an attacker who successfully exploited the vulnerability could take control of an affected system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.

In a web-based attack scenario, an attacker could host a specially crafted website that is designed to exploit the vulnerability through Internet Explorer and then convince a user to view the website, for example, by sending an email.

The security update addresses the vulnerability by modifying how the scripting engine handles objects in memory”

Disse opdateringer er valgfrie, men de skal inkluderes som en del af Microsofts næste runde af "Patch Tuesday" kumulative opdateringer i oktober.
