Astra Linux – Vulnerability in pam

A vulnerability was discovered in PAM. Secret information is stored in memory, and the attacker can trigger the victim’s program to execute by sending characters to its standard input stdin. During this process, the attacker can instruct the branch predictor to execute a ROP chain speculatively...

USN-7853-2: Linux kernel (FIPS) vulnerabilities

Jean-Claude Graf, Sandro Rüegge, Ali Hajiabadi, and Kaveh Razavi discovered that the Linux kernel contained insufficient branch predictor isolation between a guest and a userspace hypervisor for certain processors. This flaw is known as VMSCAPE. An attacker in a guest VM could possibly use this t...
