CVE-2025-13470

CVE-2025-13470 affects RNP prior to 0.18.1, where a refactoring regression left the symmetric session key for PKESK packets uninitialized beyond zeroing. The result is an all-zero session key for PKESK, allowing data encrypted with public-key encryption to be decrypted trivially, compromising con...

hpke-js 安全漏洞

hpke-js is a hybrid public key cryptographic module from the individual developer Ajitomi Daisuke. A security vulnerability exists in hpke-js versions prior to 1.7.5, which stems from a race condition in the SenderContext Seal API that could lead to a loss of message confidentiality and integrity...

PT-2025-47788

Name of the Vulnerable Software and Affected Versions RNP version 0.18.0 Description A regression in RNP version 0.18.0 causes the symmetric session key used for Public-Key Encrypted Session Key PKESK packets to remain uninitialized, resulting in it always being an all-zero byte array. This allow...

PT-2025-47653

Name of the Vulnerable Software and Affected Versions hpke-js versions prior to 1.7.5 Description The software contains a race condition in the public SenderContext Seal API. This allows the reuse of the same AEAD nonce for multiple Seal calls, potentially leading to a complete loss of...

Separating Pseudorandom Generators from Logarithmic Pseudorandom States

Pseudorandom generators PRGs are a foundational primitive in classical cryptography, underpinning a wide range of constructions. In the quantum setting, pseudorandom quantum states PRSs were proposed as a potentially weaker assumption that might serve as a substitute for PRGs in cryptographic...

Quantum Public Key Encryption for NISQ Devices

Quantum public-key encryption PKE, where public-keys and/or ciphertexts can be quantum states, is an important primitive in quantum cryptography. Unlike classical PKE e.g., RSA or ECC, quantum PKE can leverage quantum-secure cryptographic assumptions or the principles of quantum mechanics for...

Security update for libgcrypt

This update for libgcrypt fixes the following issues: CVE-2024-2236: timing-based side-channel flaw in RSA implementation can lead to decryption of RSA ciphertexts bsc1221107. Patch Instructions: To install this SUSE update use the SUSE recommended installation methods like YaST onlineupdate or...

LINE: Public-Key Encryption

We propose a public key encryption cryptosystem based on solutions of linear equation systems with predefinition of input parameters through shared secret computation for factorizable substitutions. The existence of multiple equivalent solutions for an underdetermined system of linear equations...

Anamorphic Cryptography with Elliptic Curve Methods

In 2022, Persianom, Phan and Yung outlined the creation of Anamorphic Cryptography. With this, we can create a public key to encrypt data, and then have two secret keys. These secret keys are used to decrypt the cipher into different messages. So, one secret key is given to the Dictator who must ...

The vulnerability of the IBM Robotic Process Automation software lies in its use of the RSA algorithm without the OAEP algorithm. This allows a perpetrator to disclose the protected information.

The vulnerability of the IBM Robotic Process Automation software lies in the use of the RSA algorithm instead of the OAEP algorithm. Exploiting this vulnerability allows a remote attacker to disclose the protected information...

OESA-2024-1639 iperf3 security update

Iperf is a tool for active measurements of the maximum achievable bandwidth on IP networks. It supports tuning of various parameters related to timing, protocols, and buffers. Security Fixes: iPerf3 before 3.17, when used with OpenSSL before 3.2.0 as a server with RSA authentication, allows a...

golang-fips/openssl: Memory leaks in code encrypting and decrypting RSA payloads

A memory leak flaw was found in Golang in the RSA encrypting/decrypting code, which might lead to a resource exhaustion vulnerability using attacker-controlled inputs​. The memory leak happens in github.com/golang-fips/openssl/openssl/rsa.goL113. The objects leaked are pkey​ and ctx​. That functi...

golang: crypto/tls: Timing Side Channel attack in RSA based TLS key exchanges.

A flaw was found in the Golang crypto/tls standard library. In previous versions, the package was vulnerable to a Timing Side Channel attack by observing the time it took for RSA-based TLS key exchanges, which was not constant. This flaw allows a malicious user to gather information from the...

AZL-44739 CVE-2024-2467 affecting package perl-Crypt-OpenSSL-RSA 0.33-1

A timing-based side-channel flaw exists in the perl-Crypt-OpenSSL-RSA package, which could be sufficient to recover plaintext across a network in a Bleichenbacher-style attack. To achieve successful decryption, an attacker would have to be able to send a large number of trial messages. The...
