golang: ReadUvarint and ReadVarint can read an unlimited number of bytes from invalid inputs

A flaw was found in the Go encoding/binary package. Certain invalid inputs to the ReadUvarint or the ReadVarint causes those functions to read an unlimited number of bytes from the ByteReader argument before returning an error. This flaw possibly leads to processing more input than expected. The...

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...

Using LL-HLS with byte-range addressing to achieve interoperability in low latency streaming

Introduction HTTP Adaptive Segmented HAS streaming began to be used at scale from 2008 to 2012, with the advent of Move Networks, Microsoft Smooth Streaming, Apple HLS, Adobe HDS, and MPEG DASH. With the typical 10s segment durations of the day, livestream latencies measuring latency as the time...
