Microsoft has released two out-of-program security updates to address security issues in the Windows Codecs library and the Visual Studio Code application.
The two updates come after the monthly release of security updates last Tuesday, which corrected 87 vulnerabilities.
Both new vulnerabilities allow remote code execution.
The first error has been documented as CVE-2020-17022 and Microsoft states that attackers can create malicious images that, when processed by a Windows application, can allow an attacker to run code on operating system of Windows.
All versions of Windows 10 are affected.
Microsoft has stated that an update to this library will be automatically installed on users' systems through the Microsoft Store.
Not all users are affected, but only those who have installed the optional HEVC or "HEVC from Device Manufacturer" media encoders from the Microsoft Store.
HEVC is only available through the Microsoft Store. This library is also not supported on Windows Server.
To check and see if you are using any vulnerable HEVC codec, you can look in Settings, Apps and possibilities. Select HEVC, Advanced options. Secure versions are 1.0.32762.0, 1.0.32763.0 or later.
The second error has been documented as CVE-2020-17023 and Microsoft states that attackers can create malicious files package.json files which, when loaded into Visual Studio Code, can run malicious code.
Depending on the rights of the user, the intruder code could run with administrator privileges and allow it to have full control over an infected host.
Package.json files are regularly used with libraries and JavaScript projects. JavaScript, and especially the server-side Node.js technology, is currently one of the most popular technologies.
Of course, Visual Studio Code users are advised to update the application to the latest version as soon as possible.
