The microkernel seL4 is mathematically verified for the RISC-V architecture.

Posted on

The RISC-V Foundation has reported the verification of the seL4 microkernel on RISC-V instruction set architecture systems. The verification consists of a mathematical proof of the reliability of seL4, which indicates full compliance with specifications defined in formal language. The proof of reliability allows using seL4 in mission-critical systems based on RISC-V RV64 processors, which require a higher level of reliability and guarantee the absence of […]

CROSSTalk — a vulnerability in Intel CPUs that leads to data leaks between cores

Posted on

A group of researchers from the Free University of Amsterdam has identified a new vulnerability (CVE-2020-0543) in the microarchitectural structures of Intel processors, notable for allowing the recovery of the results of certain instructions executed on another CPU core. This is the first vulnerability of the speculative execution instruction mechanism that permits data leakage between separate CPU cores (previous leaks were limited to different threads of a single core). The researchers named this issue […]

A vulnerability in UPnP suitable for amplifying DDoS attacks and scanning the internal network

Posted on

Details have been disclosed about a vulnerability (CVE-2020-12695) in the UPnP protocol that allows traffic to be sent to arbitrary recipients using the standard operation 'SUBSCRIBE.' This vulnerability has been given the code name CallStranger. It can be used for data extraction from networks protected by data leak prevention (DLP) systems, for scanning ports of computers within the internal network, and to amplify DDoS attacks using millions of connected […]

Vulnerability in GnuTLS allowing TLS 1.3 session resumption without knowledge of the key

Posted on

A vulnerability (CVE-2020-13777) has been identified in the GnuTLS library, which is used by default in many packages within Debian, including the package manager APT and many utilities, allowing a previously stopped TLS session to be resumed without the knowledge of the session key. Practically, this vulnerability can be exploited for MITM attacks. The vulnerability is caused by incorrect construction of the session ticket key — the TLS server did not bind the session key […]
