Amazon Linux 2023 : gnutls, gnutls-c++, gnutls-dane (ALAS2023-2026-1808)

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1808 advisory. Permitted name constraints were wrongfully ignored when prior CAs only had excluded name constraints, resulting in a name constraint bypass. The issue was reported in the issue tracker as 1824...

CVE-2026-42012 Gnutls: gnutls: certificate validation bypass due to improper handling of uri and srv sans

A flaw was found in gnutls. A remote attacker could exploit this vulnerability by presenting a specially crafted certificate that contains Uniform Resource Identifier URI or Service SRV Subject Alternative Names SANs. This could cause the certificate validation process to incorrectly fall back to...

DEBIAN-CVE-2026-5263

URI nameConstraints from constrained intermediate CAs are parsed but not enforced during certificate chain verification in wolfcrypt/src/asn.c. A compromised or malicious sub-CA could issue leaf certificates with URI SAN entries that violate the nameConstraints of the issuing CA, and wolfSSL woul...

CVE-2026-5263

The CVE concerns wolfSSL’s wolfcrypt (asn.c) where URI nameConstraints from constrained intermediate CAs are parsed but not enforced during certificate chain verification. This allows a compromised/malicious sub-CA to issue leaf certificates with URI SAN entries that violate the issuing CA’s name...

CVE-2021-27098

In SPIRE 0.8.1 through 0.8.4 and before versions 0.9.4, 0.10.2, 0.11.3 and 0.12.1, specially crafted requests to the FetchX509SVID RPC of SPIRE Server’s Legacy Node API can result in the possible issuance of an X.509 certificate with a URI SAN for a SPIFFE ID that the agent is not authorized to...

nodejs: Improper handling of URI Subject Alternative Names

A flaw was found in node.js where it accepted a certificate's Subject Alternative Names SAN entry, as opposed to what is specified by the HTTPS protocol. This flaw allows an active person-in-the-middle to forge a certificate and impersonate a trusted host...

Accepting arbitrary Subject Alternative Name (SAN) types unless a PKI is specifically defined to use a particular SAN type can result in bypassing name-constrained intermediates. Node.js < 12.22.9 < 14.18.3 < 16.13.2 and < 17.3.1 was accepting URI SAN types which PKIs are often not defined to use. Additionally when a protocol allows URI SANs Node.js did not match the URI correctly.Versions of Node.js with the fix for this disable the URI SAN type when checking a certificate against a hostname. This behavior can be reverted through the --security-revert command-line option.

Authorization Bypass

github.com/spiffe/spire is vulnerable to authorization bypass. The vulnerability exists as requests made to the FetchX509SVID RPC can issue a X.509 certificate with a URI SAN for a SPIFFE ID to an unauthorized agent...

CVE-2021-27098

SPIRE contains an authorization bypass vulnerability in the Legacy Node API FetchX509SVID path. Specifically, before versions 0.8.5, and prior to 0.9.4, 0.10.2, 0.11.3, and 0.12.1, specially crafted requests could cause the server to issue an X.509 certificate with a URI SAN for a SPIFFE ID that ...
