openssl: RPK server signature algorithm selection can dereference a missing certificate

A flaw was found in OpenSSL. In a server or client configuration with RFC7250 Raw Public Keys RPKs enabled, where only the private key with no certificate is configured, a NULL pointer dereference may occur when the remote peer solicits raw public keys and also sends the typically omitted...

curl: SSL session-cache peer key omits signature_algorithms: strict-sigalg handle silently resumes a permissive sibling's session

CURLOPTSSLSIGNATUREALGORITHMS policy bypass: SSL session cache key omits sigalgs, allowing a strict-sigalg handle to resume a session negotiated under a permissive policy AI disclosure This report was prepared with the assistance of an AI coding assistant Claude.

JLSEC-2026-219 Null pointer deference in openssl-src

Server or client applications that call the SSLcheckchain function during or after a TLS 1.3 handshake may crash due to a NULL pointer dereference as a result of incorrect handling of the "signaturealgorithmscert" TLS extension. The crash occurs if an invalid or unrecognised signature algorithm i...

JLSEC-2026-223 openssl-src NULL pointer Dereference in `signature_algorithms` processing

An OpenSSL TLS server may crash if sent a maliciously crafted renegotiation ClientHello message from a client. If a TLSv1.2 renegotiation ClientHello omits the signaturealgorithms extension where it was present in the initial ClientHello, but includes a signaturealgorithmscert extension then a NU...

Improperly Implemented Security Check for Standard

Overview Affected versions of this package are vulnerable to Improperly Implemented Security Check for Standard in the mbedtlssslconfsigalgs function. An attacker can reduce the security strength of cryptographic operations by forcing the use of weaker algorithms, which may result in information...
