Windows Camera Codec Pack Remote Code Execution Vulnerability - CVE-2020-16967
A remote code execution vulnerability exists when the Windows Camera Codec Pack improperly handles objects in memory. An attacker who successfully exploited the vulnerability could run arbitrary code in the context of the current user. If the current user is logged on with administrative user rights an attacker could take control of the affected system. An attacker could then install programs; view change or delete data; or create new accounts with full user rights. Users whose accounts are configured to have fewer user rights on the system could be less impacted than users who operate with administrative user rights. Exploitation of the vulnerability requires that a user open a specially crafted file with an affected version of the Windows Camera Codec Pack. In an email attack scenario an attacker could exploit the vulnerability by sending the specially crafted file to the user and convincing the user to open the file. In a web-based attack scenario an attacker could host a website (or leverage a compromised website that accepts or hosts user-provided content) containing a specially crafted file designed to exploit the vulnerability. An attacker would have no way to force users to visit the website. Instead an attacker would have to convince users to click a link typically by way of an enticement in an email or instant message and then convince them to open the specially crafted file. The security update addresses the vulnerability by correcting how the Windows Camera Codec Pack handles objects in memory.
