Understanding Binary and Data Representation with CyberChef

A significant part of reverse engineering and attacking devices relies on viewing and recognising data in various forms and working out how to decode it. We typically use Linux tools and scripts to do this, but you can make the first few steps using a really neat online tool called CyberChef. Wha...

ALPINE-CVE-2020-27672

An issue was discovered in Xen through 4.14.x allowing x86 guest OS users to cause a host OS denial of service, achieve data corruption, or possibly gain privileges by exploiting a race condition that leads to a use-after-free involving 2MiB and 1GiB superpages...

freerdp: out-of-bounds read in update_read_icon_info function

In FreeRDP greater than 1.1 and before 2.0.0, there is an out-of-bounds read in updatereadiconinfo. It allows reading a attacker-defined amount of client memory 32bit unsigned - 4GB to an intermediate buffer. This can be used to crash the client or store information for later retrieval. This has...
