CVE-2023-2820

CVE-2023-2820 affects Proofpoint Threat Response / Threat Response Auto-Pull (PTR/TRAP) via the faye endpoint. The vulnerability may allow an attacker on an adjacent network to obtain credentials to integrated services through MITM or session-traffic cryptanalysis, enabling impersonation of PTR/T...

Node.js: DiffieHellman doesn't generate keys after setting a key

DiffieHellman in Node.js did not generate new keys after setting a key, due to an issue in OpenSSL. This vulnerability could have allowed for key reuse and potential compromise of confidentiality and integrity in applications relying on DiffieHellman for security...

K16396: GnuPG vulnerability CVE-2013-4576

Security Advisory Description GnuPG 1.x before 1.4.16 generates RSA keys using sequences of introductions with certain patterns that introduce a side channel, which allows physically proximate attackers to extract RSA keys via a chosen-ciphertext attack and acoustic cryptanalysis during decryptio...

Mary Queen of Scots Letters Decrypted

This is a neat piece of historical research. The team of computer scientist George Lasry, pianist Norbert Biermann and astrophysicist Satoshi Tomokiyo--all keen cryptographers--initially thought the batch of encoded documents related to Italy, because that was how they were filed at the...

Attacking Machine Learning Systems

The field of machine learning ML security--and corresponding adversarial ML--is rapidly advancing as researchers develop sophisticated techniques to perturb, disrupt, or steal the ML model or data. It’s a heady time; because we know so little about the security of these systems, there are many...

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...

GHSA-75RW-34Q6-72CR Signature forgery in Biscuit

Impact The paper Cryptanalysis of Aggregate Γ-Signature and Practical Countermeasures in Application to Bitcoin defines a way to forge valid Γ-signatures, an algorithm that is used in the Biscuit specification version 1. It would allow an attacker to create a token with any access level. As Biscu...

Cryptanalysis of ENCSecurity’s Encryption Implementation

ENCSecurity markets a file encryption system, and its used by SanDisk, Sony, Lexar, and probably others. Despite it using AES as its algorithm, its implementation is flawed in multiple ways--and breakable. The moral is, as it always is, that implementing cryptography securely is hard. Dont roll...

CVE-2022-20742

Cisco ASA Software and Firepower Threat Defense (FTD) Software contain an IPsec IKEv2 VPN information disclosure vulnerability (CVE-2022-20742) due to improper GCM cipher implementation. An unauthenticated, remote attacker in a man-in-the-middle position can intercept encrypted messages across an...

Bunnie Huang’s Plausibly Deniable Database

Bunnie Huang has created a Plausibly Deniable Database. Most security schemes facilitate the coercive processes of an attacker because they disclose metadata about the secret data, such as the name and size of encrypted files. This allows specific and enforceable demands to be made: “Give us the...

Name of the Vulnerable Software and Affected Versions Cisco Adaptive Security Appliance ASA Software affected versions not specified Cisco Firepower Threat Defense FTD Software affected versions not specified Description The issue is related to a flaw in the implementation of Galois/Counter Mode...

Use of a Broken or Risky Cryptographic Algorithm in anonaddy/anonaddy

Description MD5 and SHA-1 are popular cryptographic hash algorithms often used to verify the integrity of messages and other data. Recent advances in cryptanalysis have discovered weaknesses in both algorithms. Consequently, MD5 and SHA-1 should no longer be relied upon to verify the authenticity...

Advisory ROSA-SA-2021-1826

Software: ed 1.9 OS: Cobalt 7.9 CVE-ID: CVE-2015-2987 CVE-Crit: MEDIUM CVE-DESC: Type74 ED before 4.0 incorrectly uses 128-bit ECB encryption for small files, making it easier for attackers to obtain plaintext data by differential cryptanalysis of a file with an original length of less than 128...

Intentional Flaw in GPRS Encryption Algorithm GEA-1

General Packet Radio Service GPRS is a mobile data standard that was widely used in the early 2000s. The first encryption algorithm for that standard was GEA-1, a stream cipher built on three linear-feedback shift registers and a non-linear combining function. Although the algorithm has a 64-bit...

CVE-2020-3585

A vulnerability in the TLS handler of Cisco Adaptive Security Appliance ASA Software and Cisco Firepower Threat Defense FTD Software for Cisco Firepower 1000 Series firewalls could allow an unauthenticated, remote attacker to gain access to sensitive information. The vulnerability is due to...

Type74 ED before 4.0 misuses 128-bit ECB encryption for small files which makes it easier for attackers to obtain plaintext data via differential cryptanalysis of a file with an original length smaller than 128 bits.
