Once Thought Safe, DDR4 Memory Shown To Be Vulnerable To 'Rowhammer' (arstechnica.com)

Posted by msmash on Saturday March 19, 2016 @05:00AM from the leaking-memory dept.

An anonymous reader writes from an Ars Technica article: Physical weaknesses in memory chips that make computers and servers susceptible to hack attacks dubbed "Rowhammer" are more exploitable than previously thought and extend to DDR4 modules, not just DDR3, according to a recently published research paper. The paper, titled How Rowhammer Could Be Used to Exploit Weaknesses in Computer Hardware (PDF), arrived at that conclusion by testing the integrity of dual in-line memory modules, or DIMMs, using diagnostic techniques that hadn't previously been applied to finding the vulnerability. The tests showed many of the DIMMs were vulnerable to a phenomenon known as "bitflipping," in which 0s were converted to 1s and vice versa.

Slashdot...always late as usual... no wonder everybody goes to HackerNews.
So why haven't you promoted my submitted story from yesterday? https://slashdot.org/submission/5686403/rowhammer-attack-now-works-on-ddr4-memory
