Description
An information disclosure issue has been found in Firefox before 83.0 and chromium before 87.0.4280.66. When drawing a transparent image on top of an unknown cross-origin image, the Skia library drawImage function took a variable amount of time depending on the content of the underlying image. This resulted in potential cross-origin information exposure of image content through timing side-channel attacks.
