A micropatch has been released for a vulnerability in Windows that allows overwriting files, even system one, with arbitrary data. The bug was disclosed on December 27 by the online alias SandboxEscaper. Microsoft has yet to release a fix for the bug. Micropatches are temporary solutions delivered in bite-size code that can solve a software security issue by streaming a fix to running processes. The microcode solution works for 64-bit Windows 10 version 1803, although users needing a variant for other Windows versions are encouraged to contact the company’s 0patch product.
