Astra Linux – Vulnerability in gnutls28
A flaw was discovered in GnuTLS. The Minerva attack is a cryptographic vulnerability that exploits deterministic behaviors in systems like GnuTLS, leading to side-channel leaks. In specific scenarios, such as when using the GNUTLSPRIVKEYFLAGREPRODUCIBLE flag, it can result in a noticeable reducti...
AZL-56720 CVE-2024-12133 affecting package gnutls for versions less than 3.8.3-4
A flaw in libtasn1 causes inefficient handling of specific certificate data. When processing a large number of elements in a certificate, libtasn1 takes much longer than expected, which can slow down or even crash the system. This flaw allows an attacker to send a specially crafted certificate,...
CVE-2024-12243 Gnutls: gnutls impacted by inefficient der decoding in libtasn1 leading to remote dos
A flaw was found in GnuTLS, which relies on libtasn1 for ASN.1 data processing. Due to an inefficient algorithm in libtasn1, decoding certain DER-encoded certificate data can take excessive time, leading to increased resource consumption. This flaw allows a remote attacker to send a specially...
GnuTLS 安全漏洞
GnuTLS is a free secure communication library for implementing SSL, TLS and DTLS protocols. A security vulnerability exists in GnuTLS. An attacker exploiting this vulnerability could send specially crafted certificates that could cause GnuTLS to become unresponsive or slow, resulting in a denial ...
ROS-20241211-10
Vulnerability of GnuTLS transport layer cryptographic library is related to difference of response time when processing RSA ciphertext in ClientKeyExchange message with correct and incorrect addition of PKCS1. PKCS1 padding. Exploitation of the vulnerability may allow a remote intruder to gain...
