ZenHammer — an attack method for manipulating memory content on AMD Zen platforms

Posted on

Researchers from the Swiss Federal Institute of Technology Zurich have developed the ZenHammer attack method, a variant of RowHammer attacks intended to modify the contents of individual bits in dynamic random-access memory (DRAM), tailored for platforms with AMD processors. Previous RowHammer attack methods were limited to Intel-based systems, but the conducted research has shown that memory cell distortions can also […]

Vulnerability in the implementation of the NFS server in FreeBSD and OpenBSD

An experiment using SQLite as a container for archiving files

Posted on

The Pack project has made an attempt to create a file archiving format based on the SQLite library and the ZSTD (Zstandard) compression algorithm. The prepared prototype, written in Pascal and distributed under the Apache 2.0 license, surpassed the most common archivers in speed while its operation was limited to reading data, compressing with the libzstd library, and executing SQL operations on […]

In Palemoon, they plan to increase CPU requirements in the ready builds.

Posted on

The developers of the Palemoon browser plan to increase CPU requirements for the ready-made builds. The reason cited is the desire to utilize AVX processor instructions to significantly speed up browser performance. This change is scheduled for the summer of 2024. To use the new builds, a processor supporting the second version of the x86-64 microarchitecture (x86_64-v2) will be required, which has been supported by processors since around 2009, starting with AMD FX […]
