Factoring 2048-bit Numbers Using 20 Million Qubits

This theoretical paper shows how to factor 2048-bit RSA moduli with a 20-million qubit quantum computer in eight hours. It's interesting work, but I don't want overstate the risk. We know from Shor's Algorithm that both factoring and discrete logs are easy to solve on a large, working quantum...

Verify JWT With JSON Web Key Set (JWKS) in API Gateway

JSON Web Tokens JWT use digital signatures to establish the authenticity of the data they contain, as well as authenticating the identity of the signer. A valid signature check ensures that any party can rely on the contents and the signatory of the JWT. This is typically accomplished by using an...

CVE-2016-8650

A flaw was found in the Linux kernel key management subsystem in which a local attacker could crash the kernel or corrupt the stack and additional memory denial of service by supplying a specially crafted RSA key. This flaw panics the machine during the verification of the RSA key...

CVE-2017-1000385

An erlang TLS server configured with cipher suites using RSA key exchange, may be vulnerable to an Adaptive Chosen Ciphertext attack AKA Bleichenbacher attack against RSA. This may result in plain-text recovery of encrypted messages and/or a man-in-the-middle MiTM attack, despite the attacker not...

CVE-2017-3738

There is an overflow bug in the AVX2 Montgomery multiplication procedure used in exponentiation with 1024-bit moduli. No EC algorithms are affected. Analysis suggests that attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not believed likely. Attack...

How to avoid getting caught in a “Groundhog Day” loop of security issues

It’s Cyber Security Awareness Month and it made me think about one of my favorite movies, called Groundhog Day. Have you ever seen it? Bill Murray is the cynical weatherman, Phil Connors, who gets stuck in an endless loop where he repeats the same day over and over again until he “participates in...

Amazon Linux 2 : nss (ALAS-2019-1305)
