CurveBall

CurveBall CVE-2020-0601 - PoC CVE-2020-0601, or commonly referred to as CurveBall, is a vulnerability in which the signature of certificates using elliptic curve cryptography ECC is not correctly verified. ECC relies on different parameters. These parameters are standardized for many curves...

CVE-2026-84465: Authentication Bypass by Spoofing

Zammad is a web based open source helpdesk/customer support system. Prior to 7.1.2, when Zammad checks the digital signature on an incoming S/MIME-signed email, it does not verify that the signing certificate is genuinely trusted, it only checks whether a certificate with a matching name is alrea...

CVE-2026-63374 AnyIO: TLSStream IDNA 2003 host name encoding enables potential TLS certificate spoofing

AnyIO is a high level asynchronous concurrency and networking framework that works on top of either Trio or asyncio. Prior to 4.14.2, connecttcp and TLSStream.wrap can validate internationalized host names after the standard library converts them with IDNA 2003 instead of IDNA 2008. When a...

CVE-2026-63374

AnyIO (a Python asynchronous networking framework) is vulnerable to TLS certificate spoofing prior to version 4.14.2 . The functions connect_tcp() and TLSStream.wrap() validate internationalized (non-ASCII) domain names using the Python standard library's IDNA 2003 encoding instead of the more ac...

Linux Distros Unpatched Vulnerability : CVE-2026-63374

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - AnyIO is a high level asynchronous concurrency and networking framework that works on top of either Trio or asyncio. Prior to 4.14.2, connecttcp and...

GHSA-82R6-8W77-94W6 AnyIO: TLSStream IDNA 2003 host name encoding enables potential TLS certificate spoofing

Impact Services using internationalized non-ASCII domain names are potentially vulnerable to TLS connections made from AnyIO's connecttcp or directly via TLSStream.wrap where the connection has through other means been hijacked and redirected to a malicious server. The attacker would obtain a...

CVE-2026-62243

A flaw was found in Netty io.netty:netty-handler. When using the SslProvider.OPENSSL client path with a plain X509TrustManager and without Unsafe-based trust-manager wrapping Java 25+, TLS hostname verification is disabled. This misconfiguration allows a man-in-the-middle attacker to present a...

aria2c accepts a server certificate with incorrect Extended Key Usage EKU. If the attackers compromise a certificate with the associated private key issued for a different purpose, they may be able to reuse it for TLS server authentication...

CVE-2026-15554

the Undertow AJP listener honours forged sslcert and isssl AJP attributes without requiring any shared-secret authentication. This enables an unauthenticated attacker with direct TCP access to port 8009 to bypass CLIENT-CERT authentication by injecting a forged X.509 certificate via the AJP...

gnutls: gnutls: Certificate validation bypass due to oversized Subject Alternative Name

A flaw was found in gnutls. When validating certificates, an oversized Subject Alternative Name SAN could cause the validation process to incorrectly fall back to checking the Common Name CN field. This could allow a remote attacker to bypass proper certificate validation, potentially leading to...

SUSE-SU-2026:2822-1 Security update for gnutls

This update for gnutls fixes the following issues - CVE-2025-14831: excessive resource consumption when verifying specially crafted malicious certificates containing a large number of name constraints and SANs bsc1257960. - CVE-2026-3833: incorrectly accepted domain names due to comparison during...

K000161963: Golang vulnerability CVE-2025-61727

Security Advisory Description An excluded subdomain constraint in a certificate chain does not restrict the usage of wildcard SANs in the leaf certificate. For example a constraint that excludes the subdomain test.example . com does not prevent a leaf certificate from claiming the SAN .example.co...

CVE-2026-56020

The CVE-2026-56020 affects the Webmin HTTP server (miniserv.pl). An unauthenticated attacker can bypass authentication by sending a forged HTTP header to impersonate any user who has an SSL client certificate configured, effectively spoofing certificate DNs to gain access. This is a network-based...

Webmin multiple vulnerabilities
