Microsoft Edge, Teams get fixes for zero-days in open-source libraries
2023-10-03 14:54

Microsoft released emergency security updates for Edge, Teams, and Skype to patch two zero-day vulnerabilities in open-source libraries used by the three products.

The libwebp library is used by a large number of projects for encoding and decoding images in the WebP format, including modern web browsers like Safari, Mozilla Firefox, Microsoft Edge, Opera, and the native Android web browsers, as well as popular apps like 1Password and Signal.

"Microsoft is aware and has released patches associated with the two Open-Source Software security vulnerabilities, CVE-2023-4863 and CVE-2023-5217," Redmond revealed in a Microsoft Security Response Center advisory.

The two security flaws only affect a limited number of Microsoft products, with the company patching Microsoft Edge, Microsoft Teams for Desktop, Skype for Desktop, and Webp Image Extensions against CVE-2023-4863 and Microsoft Edge against CVE-2023-5217.

The security update will not be installed if Microsoft Store automatic updates are disabled.
