In QEMU 1:4.1-1, 1:2.1+dfsg-12+deb8u6, 1:2.8+dfsg-6+deb9u8, 1:3.1+dfsg-8deb10u1, 1:3.1+dfsg-8+deb10u2, and 1:2.1+dfsg-12+deb8u12 fixed, when executing script in lsiexecutescript, the LSI scsi adapter emulator advances 's-dsp' index to read next opcode. This can lead to an infinite loop if the nex...
QEMU: slirp: heap buffer overflow in tcp_emu()
A heap buffer overflow issue was found in the SLiRP networking implementation of the QEMU emulator. It occurs in tcpemu routine while emulating the Identification protocol and copying message data to a socket buffer. A user or process could use this flaw to crash the QEMU process on the host...
QEMU: pcnet: integer overflow leads to buffer overflow
An integer overflow issue was found in the AMD PC-Net II NIC emulation in QEMU. It could occur while receiving packets, if the size value was greater than INTMAX. Such overflow would lead to stack buffer overflow issue. A user inside guest could use this flaw to crash the QEMU process resulting i...
CVE-2019-5609
The CVE-2019-5609 issue affects FreeBSD with the bhyve e1000 device: when TCP segmentation offload is requested for a transmitted packet, the guest can influence the size of an on‑stack buffer, enabling potential memory corruption in the bhyve host process. Affected versions include FreeBSD 12.0-...

UPDATE: MITRE CALDERA 2.3.0
PenTestIT RSS Feed A month ago, MITRE Caldera 2.2.0 was released and a couple of days back now MITRE CALDERA 2.3.0 was released as well. If you remember, I wrote briefly about this automated adversary emulation system in my post titled – List of Adversary Emulation Tools. A lot of changes have be...
The Twists and Turns on the Road to Binee
On August 10, we introduced Binee—a binary emulation environment—to the world at DEFCON and, in an earlier blog, we shared a little bit of how and why we created this tool. Today, Binee is a tool that malware researchers can use as part of their reverse engineering processes. It’s an open-sourced...

Binee: Outsmarting Malware with Next-Generation Process Emulation
The Problem with Malware Analysis Threat researchers get thousands of samples of malware every day and, as every researcher knows, it is very difficult to analyze them in a way that allows for intelligent decisions regarding whether a sample’s reputation is good or bad. There are already some qui...
FreeBSD : FreeBSD -- Privilege escalation in cd(4) driver (14a3b376-b30a-11e9-a87f-a4badb2f4699)
To implement one particular ioctl, the Linux emulation code used a special interface present in the cd4 driver which allows it to copy subchannel information directly to a kernel address. This interface was erroneously made accessible to userland, allowing users with read access to a cd4 device t...

Finding Evil in Windows 10 Compressed Memory, Part Three: Automating Undocumented Structure Extraction
This is the final post in the three-part series: Finding Evil in Windows 10 Compressed Memory. In the first post Volatility and Rekall Tools, the FLARE team introduced updates to both memory forensic toolkits. These updates enabled these open source tools to analyze previously inaccessible...
kernel: kvm: guest userspace to guest kernel write
A flaw was found in the way Linux kernel KVM hypervisor emulated instructions such as sgdt/sidt/fxsave/fxrstor. It did not check current privilegeCPL level while emulating unprivileged instructions. An unprivileged guest user/process could use this flaw to potentially escalate privileges inside...
