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...

K000160551: OpenSSL vulnerability CVE-2025-66199

Security Advisory Description Issue summary: A TLS 1.3 connection using certificate compression can be forced to allocate a large buffer before decompression without checking against the configured certificate size limit. Impact summary: An attacker can cause per-connection memory allocations of ...

crypto/tls: crypto/tls: Incorrect certificate validation during TLS session resumption

A flaw was found in the crypto/tls component. This vulnerability occurs during Transport Layer Security TLS session resumption when certificate authority CA settings are modified between the initial and resumed handshakes. An attacker could exploit this to bypass certificate validation, allowing ...
