Description

This strike exploits a vulnerability in the Apple Safari browser. Specifically the vulnerability exists when compiling WebAssembly source buffers in WebKit. The source buffer is copied to a read only buffer, and if this buffer is a view, the offset is added to the buffer which can potentially allow for heap memory to be read off of the source. This can result in a denial of service condition in the browser or possibly remote code execution.
