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...

EUVD-2026-21070

Missing hash/digest size and OID checks allow digests smaller than allowed when verifying ECDSA certificates, or smaller than is appropriate for the relevant key type, to be accepted by signature verification functions. This could lead to reduced security of ECDSA certificate-based authentication...

CVE-2026-40070 bsv-sdk and bsv-wallet persist unverified certifier signatures in acquire_certificate (direct and issuance paths)

BSV Ruby SDK is the Ruby SDK for the BSV blockchain. From 0.3.1 to before 0.8.2, BSV::Wallet::WalletClientacquirecertificate persists certificate records to storage without verifying the certifier's signature over the certificate contents. In acquisitionprotocol: 'direct', the caller supplies all...

crypto/x509: Panic in name constraint checking for malformed certificates in crypto/x509

A certificate validation flaw has been discovered in the golang crypto/x509 module. Certificate verification can panic when a certificate in the chain has an empty DNS name and another certificate in the chain has excluded name constraints. This can crash programs that are either directly verifyi...

CVE-2026-34179

CVE-2026-34179 affects Canonical LXD versions 4.12–6.7. The vulnerability is in the doCertificateUpdate function (lxd/certificates.go) where the Type field is not validated for PUT/PATCH requests to /1.0/certificates/{fingerprint} for restricted TLS certificate users, enabling a remote authentica...

CVE-2026-34179

In Canonical LXD versions 4.12 through 6.7, the doCertificateUpdate function in lxd/certificates.go does not validate the Type field when handling PUT/PATCH requests to /1.0/certificates/fingerprint for restricted TLS certificate users, allowing a remote authenticated attacker to escalate...

openssl: OpenSSL: Heap buffer overflow on 32-bit systems from large X.509 certificate processing

A flaw was found in OpenSSL. This vulnerability, a heap buffer overflow, affects 32-bit systems when processing an unusually large X.509 certificate. If an application or service attempts to print or log such a specially crafted certificate, it could lead to a system crash or potentially allow an...
