CVE-2026-42304

Twisted is an event-based framework for internet applications, supporting Python 3.6+. Prior to 26.4.0rc2, the twisted.names module is vulnerable to a Denial of Service DoS attack via resource exhaustion during DNS name decompression. A remote, unauthenticated attacker can exploit this by sending...

USN-8380-1 twisted vulnerability

It was discovered that Twisted incorrectly handled DNS name decompression. A remote attacker could possibly use this issue to cause Twisted to consume excessive resources, leading to a denial of service...

gnutls: GnuTLS: Policy bypass due to case-sensitive nameConstraints comparison

A flaw was found in gnutls. This vulnerability occurs because gnutls performs case-sensitive comparisons of nameConstraints labels, specifically for dNSName DNS or rfc822Name email constraints within excludedSubtrees or permittedSubtrees. A remote attacker can exploit this by crafting a leaf...

Amazon Linux 2023 : gnutls, gnutls-c++, gnutls-dane (ALAS2023-2026-1757)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1757 advisory. GnuTLS didn't check that DTLS fragments claimed a consistent messagelength value. Additionally, a crucial array size check was missing, enabling an attacker to cause a heap overwrite...

CLSA-2026-1779107085 gnutls: Fix of CVE-2026-3833

GHSA-GRGV-6HW6-V9G4 Twisted has a Denial of Service (DoS) in twisted.names via Crafted DNS Compression Pointer Chains

Details The twisted.names module is vulnerable to a Denial of Service DoS attack via resource exhaustion during DNS name decompression. A remote, unauthenticated attacker can exploit this by sending a crafted TCP DNS packet containing deeply chained compression pointers. This flaw bypasses previo...

Improper Handling of Case Sensitivity

Overview Affected versions of this package are vulnerable to Improper Handling of Case Sensitivity in the enforcement of X.509 nameConstraints due to case-sensitive comparisons for dNSName and the domain portion of rfc822Name. An attacker can gain unauthorized certificate validation and potential...

webpki: Name constraints were accepted for certificates asserting a wildcard name

Permitted subtree name constraints for DNS names were accepted for certificates asserting a wildcard name. This was incorrect because, given a name constraint of accept.example.com, .example.com could feasibly allow a name of reject.example.com which is outside the constraint. This is very simila...

SUSE CVE-2026-32884

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 allowable DNS names, if no subject alternative name is defined in the end-entity certificate Botan would check that the CN was allowed by t...
