CVE-2022-2294: 
vulnerability analysis and mitigation

CVE-2022-2294 is a heap buffer overflow vulnerability discovered in WebRTC component of Google Chrome prior to version 103.0.5060.114. The vulnerability was reported by Jan Vojtesek from the Avast Threat Intelligence team on July 1, 2022, and was publicly disclosed on July 4, 2022. This security flaw affected Google Chrome and other Chromium-based browsers, as well as WebKit-based applications that had LibWebRTC enabled (Chrome Release, NVD).

The vulnerability is classified as a heap buffer overflow in the WebRTC (Web Real-Time Communication) component. It allows a remote attacker to potentially exploit heap corruption through a specially crafted HTML page. The issue specifically affects the LibWebRTC implementation, which is used for real-time communication features in web browsers (WebKit Advisory).

The vulnerability could lead to remote code execution through heap corruption if successfully exploited. This is particularly severe as it could allow attackers to execute arbitrary code on affected systems through maliciously crafted web pages (Chrome Release).

The vulnerability was patched in Google Chrome version 103.0.5060.114. Users and organizations are strongly advised to update to this version or later. For WebKitGTK and WPE WebKit users, the fix was included in version 2.36.5, though it only affects builds with USE_LIBWEBRTC enabled (WebKit Advisory, Chrome Release).
