OpenSSL: Excessive time spent checking DH q parameter value

A vulnerability was found in OpenSSL. This security issue occurs because the applications that use the DHcheck, DHcheckex, or EVPPKEYparamcheck functions to check a DH key or DH parameters may experience long delays. Where the key or parameters that are being checked have been obtained from an...

The vulnerability of the Golang programming language’s crypto/tls package, which allows a hacker to trigger a service failure.

The vulnerability of the Golang programming language’s crypto/tls package is related to uncontrolled resource consumption. Exploiting this vulnerability can allow a malicious actor to cause service failures when sending TLS authentication records...

The vulnerabilities of the functions load_pem_pkcs7_certificates() and load_der_pkcs7_certificates() in the cryptography package allow a perpetrator to cause a service failure.

The vulnerability of the loadpempkcs7certificates and loadderpkcs7certificates functions in the cryptography package is related to the passing of NULL pointers. Exploiting this vulnerability could allow a remote attacker to cause service interruptions...

ALPINE-CVE-2024-28960

An issue was discovered in Mbed TLS 2.18.0 through 2.28.x before 2.28.8 and 3.x before 3.6.0, and Mbed Crypto. The PSA Crypto API mishandles shared memory...

DEBIAN-CVE-2024-28102

JWCrypto implements JWK, JWS, and JWE specifications using python-cryptography. Prior to version 1.5.6, an attacker can cause a denial of service attack by passing in a malicious JWE Token with a high compression ratio. When the server processes this token, it will consume a lot of memory and...

The vulnerability of the deserialize() function in the Jwcrypto Python library, which allows a hacker to trigger a denial-of-service attack.

The vulnerability of the deserialize function in the JavaScript library used by Jwcrypto for cryptography involves an uncontrolled resource consumption. Exploiting this vulnerability could allow a malicious actor, operating remotely, to cause service failure by sending a specially created JWE tok...

CVE-2024-20833

Use after free vulnerability in pubcryptorecvmsg prior to SMR Mar-2024 Release 1 due to race condition allows local attackers with system privilege to cause memory corruption...

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...

GHSA-6VQW-3V5J-54X4 cryptography NULL pointer dereference with pkcs12.serialize_key_and_certificates when called with a non-matching certificate and private key and an hmac_hash override

If pkcs12.serializekeyandcertificates is called with both: 1. A certificate whose public key did not match the provided private key 2. An encryptionalgorithm with hmachash set via PrivateFormat.PKCS12.encryptionbuilder.hmachash... Then a NULL pointer dereference would occur, crashing the Python...

UBUNTU-CVE-2023-5992

A vulnerability was found in OpenSC where PKCS1 encryption padding removal is not implemented as side-channel resistant. This issue may result in the potential leak of private data...

Medium: nss-softokn

Issue Overview: It was discovered that the numerical library used in NSS for RSA cryptography leaks information whether high order bits of the RSA decryption result are zero. This information can be used to mount a Bleichenbacher or Manger like attack against all RSA decryption operations. As the...

crypto-js: PBKDF2 1,000 times weaker than specified in 1993 and 1.3M times weaker than current standard

A vulnerability was found in crypto-js in how PBKDF2 is 1,000 times weaker than originally specified in 1993 and at least 1,300,000 times weaker than the current industry standard. This issue is because both default to SHA1, a cryptographic hash algorithm considered insecure since at least 2005,...

nss: timing attack against RSA decryption

It was discovered that the numerical library used in NSS for RSA cryptography leaks information whether high order bits of the RSA decryption result are zero. This information can be used to mount a Bleichenbacher or Manger like attack against all RSA decryption operations. As the leak happens...

Cryptography has a denial of service vulnerability

Cryptography is a Python library that provides cryptography functionality. Cryptography suffers from a denial of service vulnerability that can be exploited by an attacker to cause a program to crash...

PYSEC-2023-254

cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Calling loadpempkcs7certificates or loadderpkcs7certificates could lead to a NULL-pointer dereference and segfault. Exploitation of this vulnerability poses a serious risk of Denial of Service...
