Thinking Outside the Bochs: Code Grafting to Unpack Malware in Emulation

This blog post continues the FLARE script series with a discussion of patching IDA Pro database files IDBs to interactively emulate code. While the fastest way to analyze or unpack malware is often to run it, malware won’t always successfully execute in a VM. I use IDA Pro’s Bochs integration in...

CVE-2019-15034

A buffer overflow flaw was found in the way the Bochs display driver of QEMU handled the PCIe extended configuration space when the device is connected to a PCIe bus. Accessing the PCIe extended config space could overflow the conventional PCI config space buffer due to limited memory allocation...

QEMU Buffer Overflow Vulnerability (CNVD-2020-19909)

QEMU Quick Emulator is a set of simulation processor software by French software developer Fabrice Bellard. The software is fast, cross-platform and other characteristics. A buffer overflow vulnerability exists in the hw/display/bochs-display.c file in QEMU version 4.0.0. The vulnerability stems...
