Mozilla Firefox ESR < 45.8.0 RCE

Versions of Mozilla Firefox ESR earlier than 45.8.0 are unpatched for an integer overflow condition in the ‘nsGlobalWindow::CreateImageBitmap()’ function in ‘dom/base/nsGlobalWindow.cpp’ that is triggered as certain input is not properly validated. This may allow a context-dependent attacker to corrupt memory and execute arbitrary code.
