Towards Remote Attestation of Microarchitectural Attacks: The Case of Rowhammer

Microarchitectural vulnerabilities increasingly undermine the assumption that hardware can be treated as a reliable root of trust. Prevention mechanisms often lag behind evolving attack techniques, leaving deployed systems unable to assume continued trustworthiness. We propose a shift from...

php: heap-based buffer overflow in array_merge()

A flaw was found in PHP. A heap-based buffer overflow occurs in the arraymerge function when the total element count of packed arrays exceeds the 32-bit limit or the internal HTMAXSIZE due to an integer overflow in the precomputation of element counts using the zendhashnumelements function, causi...

New "LeakyLooker" Flaws in Google Looker Studio Could Enable Cross-Tenant SQL Queries

Cybersecurity researchers have disclosed nine cross-tenant vulnerabilities in Google Looker Studio that could have permitted attackers to run arbitrary SQL queries on victims' databases and exfiltrate sensitive data within organizations' Google Cloud environments. The shortcomings have been...
