XQUIC 安全漏洞

XQUIC is an open-source cross-platform implementation code base for QUIC and HTTP/3 protocols developed by Alibaba. Versions of XQUIC 1.8.3 and earlier contain security vulnerabilities. These vulnerabilities stem from improper input validation and encryption signature verification, which may lead...

openssl: OpenSSL: Denial of Service via NULL pointer dereference in QUIC protocol handling

A flaw was found in openssl. A remote attacker could trigger a NULL pointer dereference by sending an unknown or unsupported cipher ID during the client hello callback in applications using the QUIC Quick UDP Internet Connections protocol. This vulnerability, occurring when the SSLCIPHERfind...

curl: Public key pinning bypass via QUIC and GnuTLS allows server impersonation

A flaw was found in curl. When configured to use public key pinning with QUIC connections and GnuTLS, and with standard certificate verification explicitly disabled, curl could bypass the intended public key check. This oversight allows a malicious server to impersonate a legitimate one,...

SUSE CVE-2026-24030

An attacker might be able to trick DNSdist into allocating too much memory while processing DNS over QUIC or DNS over HTTP/3 payloads, resulting in a denial of service. In setups with a large quantity of memory available this usually results in an exception and the QUIC connection is properly...

Study of Post Quantum Status of Widely Used Protocols

The advent of quantum computing poses significant threats to classical public-key cryptographic primitives such as RSA and elliptic-curve cryptography. As many critical network and security protocols depend on these primitives for key exchange and authentication, there is an urgent need to...
