Arm: Completion of memory accesses not guaranteed by completion of a TLBI

ISSUE DESCRIPTION A hardware issue has been identified in certain Arm CPU designs. A broadcast TLBI on one PE may complete before affected memory accesses on another PE are globally observed. This may permit bypass of Stage 1 translation, Stage 2 translation, or GPT protection. The erratum occurs...

New FROST Attack Lets Websites Track What Sites and Apps You Open via SSD Timing

A malicious website can work out which sites you visit and which apps you open, using nothing but JavaScript and the timing of your SSD. The attack, called FROST , needs no native code, no extension, and no permission prompt. You open the page, leave the tab sitting there, and it watches the driv...

Hiding the Trees in the Forest: Building Network Covert Channels with Hash-Based Covert Carrier Filtering

As an effective anti-censorship mechanism, network covert channels can provide data privacy protection and ensure communication security. However, the covertness of existing network covert channels primarily depends on the secrecy of their covert algorithms. With the increasing depth of research ...

FROST: Fingerprinting Remotely Using OPFS-based SSD Timing

Prior work showed that variations in SSD access time can be used to leak information about user activity, e.g., the websites a user accesses, and for covert data transmission. To achieve this, SSD contention side channels require accurate high-resolution timing measurements of I/O operations, e.g...

FreeBSD-kernel -- ASLR bypass for setuid executables via procctl(2)

Problem Description: The ELF image activator cleared per-process ASLR preference flags for setuid binaries after the code that computes the PIE base address, rather than before. As a result, a user-requested ASLR disable was still in effect at the point where the base address was chosen. Impact: ...
