RAMBleed Side-Channel Attack Exposes Privileged Memory

A team of academic researchers has discovered a follow-on to the Rowhammer class of attacks that allows attackers to read memory data on a target Windows computer, without actually accessing the memory itself. The method is dubbed RAMBleed. Andrew Kwong and Daniel Genkin at the University of...

RAMBleed Attack – Flip Bits to Steal Sensitive Data from Computer Memory

A team of cybersecurity researchers yesterday revealed details of a new side-channel attack on dynamic random-access memory DRAM that could allow malicious programs installed on a modern system to read sensitive memory data from other processes running on the same hardware. Dubbed RAMBleed and...

Side-channel Attack

httpd is vulnerable to side-channel attack. An implementation flaw was discovered in multiple cryptographic libraries that allows a side-channel based attacker to recover ECDSA or DSA private keys. When these cryptographic libraries use the private key to create a signature, such as for a TLS or...

Amazon Linux 2 : kernel (ALAS-2019-1214)

A flaw was found in the Linux kernel's freescale hypervisor manager implementation. A parameter passed via to an ioctl was incorrectly validated and used in size calculations for the page size calculation. An attacker can use this flaw to crash the system or corrupt memory or, possibly, create...

Ubuntu 16.04 LTS / 18.04 LTS : GnuTLS vulnerabilities (USN-3999-1)

The remote Ubuntu 16.04 LTS / 18.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-3999-1 advisory. Eyal Ronen, Kenneth G. Paterson, and Adi Shamir discovered that GnuTLS was vulnerable to a timing side- channel attack known as the Lucky...
