php: DirectoryIterator class accepts filenames with embedded \0 byte and treats them as terminating at that byte

In PHP versions 7.2.x below 7.2.26, 7.3.x below 7.3.13 and 7.4.0, PHP DirectoryIterator class accepts filenames with embedded \0 byte and treats them as terminating at that byte. This could lead to security vulnerabilities, e.g. in applications checking paths that the code is allowed to access...

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...

Alternatives to Animated GIFs

We have all been amused by animated GIFs on lots of websites -- dancing babies, cute cats, flying birds, funny memes, and countless others. Despite their popularity, animated GIFs can be very heavy and can contribute significantly to page performance issues. How significantly? We have seen...

Mozilla: DoH did not filter IPv4 mapped IP Addresses

When DNS over HTTPS is in use, it intentionally filters RFC1918 and related IP ranges from the responses as these do not make sense coming from a DoH resolver. However when an IPv4 address was mapped through IPv6, these addresses were erroneously let through, leading to a potential DNS Rebinding...

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...
