Microsoft has issued out-of-band patches for two “important” severity vulnerabilities, which if exploited could allow for remote code execution.
One flaw (CVE-2020-17023) exists in Microsoft’s Visual Studio Code is a free source-code editor made by Microsoft for Windows, Linux and macOS. The other (CVE-2020-17022) is in the Microsoft Windows Codecs Library; the codecs module provides stream and file interfaces for transcoding data in Windows programs.
“Microsoft has released security updates to address remote code execution vulnerabilities affecting Windows Codecs Library and Visual Studio Code,” according to a Friday CISA alert on the patches. “An attacker could exploit these vulnerabilities to take control of an affected system.”
Neither flaw has been observed being exploited in the wild according to Microsoft. Microsoft also did not offer mitigations or workarounds for other flaws – but updates will be automatically installed for users.
“Affected customers will be automatically updated by Microsoft Store,” according to Microsoft. “Customers do not need to take any action to receive the update.”
In the case of these bugs, “servicing for store apps/components does not follow the monthly ‘Update Tuesday’ cadence, but are offered whenever necessary,” according to Microsoft.
