golang: crypto/elliptic: IsOnCurve returns true for invalid field elements

A flaw was found in the elliptic package of the crypto library in golang when the IsOnCurve function could return true for invalid field elements. This flaw allows an attacker to take advantage of this undefined behavior, affecting the availability and integrity of the resource...

golang: crypto/elliptic: panic caused by oversized scalar

An integer overflow flaw was found in Golang's crypto/elliptic library. This flaw allows an attacker to use a crafted scaler input longer than 32 bytes, causing P256.ScalarMult or P256.ScalarBaseMult to panic, leading to a loss of availability...

Intel IPP Cryptography 安全漏洞

Intel IPP Cryptography is an Intel Integrated Performance Primitives IPP cryptography software library from Intel Corporation. A security vulnerability exists in Intel IPP Cryptography. An attacker could exploit this vulnerability to disclose sensitive information...

Intel® IPP Cryptography Advisory

Summary: A potential security vulnerability in an Intel® Integrated Performance Primitives IPP Cryptography software library may allow information disclosure. Intel is releasing software updates to mitigate this potential vulnerability. Vulnerability Details: CVEID: CVE-2022-26083 Description:...

NIST’s Post-Quantum Cryptography Standards

Quantum computing is a completely new paradigm for computers. A quantum computer uses quantum properties such as superposition, which allows a qubit a quantum bit to be neither 0 nor 1, but something much more complicated. In theory, such a computer can solve problems too complex for conventional...

Slack Resets Passwords After a Bug Exposed Hashed Passwords for Some Users

Slack said it took the step of resetting passwords for about 0.5% of its users after a flaw exposed salted password hashes when creating or revoking shared invitation links for workspaces. "When a user performed either of these actions, Slack transmitted a hashed version of their password to othe...

A vulnerability found in gnutls. This security flaw happens because of a double free error occurs during verification of pkcs7 signatures in gnutls_pkcs7_verify function.

A Wide Reduction Trick

In line with the original spirit of Cryptography Dispatches, this is a quick1 issue to talk about a neat bit of cryptography engineering I encountered. The structure of an ECC implementation Elliptic curve cryptography implementations all roughly share the following structure: theres a base field...

SIKE Broken

SIKE is one of the new algorithms that NIST recently added to the post-quantum cryptography competition. It was just broken, really badly. We present an efficient key recovery attack on the Supersingular Isogeny Diffie­-Hellman protocol SIDH, based on a "glue-and-split" theorem due to Kani. Our...

Single-Core CPU Cracked Post-Quantum Encryption Candidate Algorithm in Just an Hour

A late-stage candidate encryption algorithm that was meant to withstand decryption by powerful quantum computers in the future has been trivially cracked by using a computer running Intel Xeon CPU in an hour's time. The algorithm in question is SIKE — short for Supersingular Isogeny Key...

ALSA-2022:5818 Moderate: openssl security update
