HTTP/2: large amount of data requests leads to denial of service

A flaw was found in HTTP/2. An attacker can request a large amount of data by manipulating window size and stream priority to force the server to queue the data in 1-byte chunks. Depending on how efficiently this data is queued, this queue can consume excess CPU, memory, or both, leading to a...

Amazon Linux 2 : nghttp2 (ALAS-2019-1298) (Data Dribble) (Resource Loop)

Some HTTP/2 implementations are vulnerable to window size manipulation and stream prioritization manipulation, potentially leading to a denial of service. The attacker requests a large amount of data from a specified resource over multiple streams. They manipulate window size and stream priority ...

libyal libfwsi Buffer Overflow Vulnerability

libyal libfwsi is a library for accessing the Windows Shell. The 'libfwsiextensionblockcopyfrombytestream' function in the libfwsiextensionblock.c file in versions prior to libyal libfwsi 20191006 has a Buffer overflow vulnerability, which arises when a networked system or product performs an...

Name of the Vulnerable Software and Affected Versions: libyal libfwsi versions prior to 20191006 Description: The issue is related to a heap-based buffer over-read in the libfwsi extension block copy from byte stream function in libfwsi extension block.c. This occurs because the rejection of an...

More Cryptanalysis of Solitaire

In 1999, I invented the Solitaire encryption algorithm, designed to manually encrypt data using a deck of cards. It was written into the plot of Neal Stephenson's novel Cryptonomicon, and I even wrote an afterward to the book describing the cipher. I don't talk about it much, mostly because I mad...
