Cef · Cef · CVE-2024-21639
**Name of the Vulnerable Software and Affected Versions**
CEF (Chromium Embedded Framework) versions prior to the version containing commit 1f55d2e
**Description**
The issue arises from the `CefLayeredWindowUpdaterOSR::OnAllocatedSharedMemory` function not checking the size of the shared memory, leading to an out-of-bounds read outside the sandbox. This is a problem in CEF, a framework for embedding Chromium-based browsers in other applications.
**Recommendations**
For versions prior to the one containing commit 1f55d2e, update to a version that includes the patch commit 1f55d2e to resolve the issue. As a temporary workaround, consider restricting access to the `CefLayeredWindowUpdaterOSR::OnAllocatedSharedMemory` function until a patch is applied.
