Security News > 2020 > July > Microsoft fixes two RCE flaws affecting Windows 10 machines

Microsoft has released fixes for two remote code execution vulnerabilities in the Microsoft Windows Codecs Library on Windows 10 machines.
Both flaws - CVE-2020-1425 and CVE-2020-1457 - arose because of the way the Microsoft Windows Codecs Library handled objects in memory.
What initially seemed like critical out-of-band patches for Windows 10 and Windows Server 2019 systems turned out to be slightly less urgent patches since the flaws affect only Windows 10 systems and only those users who have installed the optional HEVC or "HEVC from Device Manufacturer" media codecs from Microsoft Store, limiting thusly the pool of machines open to attack.
Affected customers also didn't have to do anything to receive the update, as they were automatically updated by Microsoft Store.
Microsoft has noted that users who have turned off automatic updating for Microsoft Store apps should check for them with the Microsoft Store App or risk going without them.
