Qemu: display: cirrus: OOB read access issue

An out-of-bounds access issue was found in QEMU's Cirrus CLGD 54xx VGA Emulator support. The vulnerability could occur while copying VGA data using bitblt functions for example, cirrusbitbltropfwdtransp. A privileged user inside a guest could use this flaw to crash the QEMU process, resulting in...

Writing a libemu/Unicorn Compatability Layer

In this post we are going to take a quick look at what it takes to write a libemu compatibility layer for the Unicorn engine. In the course of this work, we will also import the libemu Win32 environment to run under Unicorn. For a bit of background, libemu is a lightweight x86 emulator written in...
