Erlang/OTP 安全漏洞

Erlang/OTP is an open-source JavaScript library for handling exceptions. This library can catch exceptions caused by node.js’s built-in APIs. There is a security vulnerability in Erlang/OTP, which stems from improper certificate verification in the publickey module. This vulnerability allows...

gnutls: gnutls: Security bypass due to incorrect name constraint handling

A flaw was found in gnutls. This vulnerability occurs because permitted name constraints were incorrectly ignored when previous Certificate Authorities CAs only had excluded name constraints. A remote attacker could exploit this to bypass critical name constraint checks during certificate...

Ubuntu 22.04 LTS / 24.04 LTS / 25.10 / 26.04 LTS : GnuTLS vulnerabilities (USN-8284-1)

The remote Ubuntu 22.04 LTS / 24.04 LTS / 25.10 / 26.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-8284-1 advisory. Joshua Rogers discovered that GnuTLS did not properly handle malformed DTLS handshake fragments in certain cases. A remot...

Red Hat Product Security has rated this update as having a security impact of Important. A Common Vulnerability Scoring System CVSS base score, which gives a detailed severity rating, ...

crypto/x509: golang: Go crypto/x509: Certificate validation bypass due to incorrect DNS constraint application

A flaw was found in the crypto/x509 package within Go golang. When verifying a certificate chain, excluded DNS Domain Name System constraints are not correctly applied to wildcard DNS Subject Alternative Names SANs if the case of the SAN differs from the constraint. This oversight could allow an...

Unity Linux 20.1050e / 20.1060e / 20.1070e Security Update: golang (UTSA-2026-016810)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-016810 advisory. Due to the design of the name constraint checking algorithm, the processing time of some inputs scale non- linearly with respect to the size of the certificate. This...

CVE-2026-42011

A flaw was found in gnutls. This vulnerability occurs because permitted name constraints were incorrectly ignored when previous Certificate Authorities CAs only had excluded name constraints. A remote attacker could exploit this to bypass critical name constraint checks during certificate...

Security Bulletin: IBM Watson Speech Services Cartridge is vulnerable to Inefficient Algorithmic Complexity in crypto/x509 [CVE-2025-58187]

Summary IBM Watson Speech Services Cartridge is vulnerable to Inefficient Algorithmic Complexity in crypto/x509, due to non-linear processing time of some inputs scale with respect to the size of the certificate CVE-2025-58187. Crypto/x509 is used in our speech utilities. This vulnerabilitiy has...

CLEANSTART-2026-QZ16523 Due to the design of the name constraint checking algorithm, the processing time of some inputs scale non-linearly with respect to the size of the certificate

Multiple security vulnerabilities affect the modelmesh-runtime-adapter package. Due to the design of the name constraint checking algorithm, the processing time of some inputs scale non-linearly with respect to the size of the certificate. See references for individual vulnerability details...

Linux Distros Unpatched Vulnerability : CVE-2026-32884

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Botan is a C++ cryptography library. Prior to version 3.11.0, during processing of an X.509 certificate path using name constraints which restrict the set of...

CVE-2026-34073

A flaw was found in the cryptography library. This vulnerability occurs because DNS Domain Name System name constraints were not properly validated against the "peer name" during certificate validation, only against Subject Alternative Names SANs within child certificates. This oversight could...

PYSEC-2026-35

cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Prior to version 46.0.6, DNS name constraints were only validated against SANs within child certificates, and not the "peer name" presented during each validation. Consequently, cryptography...
