UBUNTU-CVE-2026-69248

cryptography is a package designed to expose cryptographic primitives and recipes to Python developers. Prior to 49.0.0, if an intermediate constrained CA permits the DNS name foo.example.com, and the leaf certificate has a wildcard in its DNS SAN of .example.com, python-cryptography's verifier...

UBUNTU-CVE-2026-67293

FreeRDP before 3.29.0 affected versions = 3.28.0 contains an improper certificate hostname validation vulnerability. The TLS hostname matcher tlsmatchhostname in libfreerdp/crypto/tls.c treats a wildcard pattern such as .example.com as matching any hostname ending in .example.com, so it incorrect...

Security Bulletin: There is a vulnerability in vertx-core-4.5.24.jar used by IBM Maximo Manage application in IBM Maximo Application Suite (CVE-2026-6860)

Summary There is a vulnerability in vertx-core-4.5.24.jar used by IBM Maximo Manage application in IBM Maximo Application Suite. Vulnerability Details CVEID:CVE-2026-6860 DESCRIPTION: A TCP client can perform a TLS handshake and present the server name extension with a server name that is accepte...

CVE-2026-6860

A flaw was found in eclipse-vertx/vert.x. A remote attacker can exploit this vulnerability by performing a Transport Layer Security TLS handshake and presenting a server name extension with a server wildcard name. This can lead to a denial of service DoS condition, impacting the availability of t...

CVE-2026-6860

A TCP client can perform a TLS handshake and present the server name extension with a server name that is accepted by a server wildcard name, e.g. if the server is configured with a certificate accepting .example.com, any XYZ.example.com where xyz is a valid name can be used...

CVE-2026-6860

CVE-2026-6860 describes a TLS SNI handling weakness where a TCP client can present an SNI that matches a server wildcard certificate (e.g., *.example.com) and be accepted by the server, allowing any XYZ.example.com under the wildcard to be used. The CVSS 4.0 vector yields a NETWORK, LOW complexit...

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...
