Security vulnerabilities and automated fixes for quic issues

A high-severity vulnerability (GHSA-4w2j-m93h-cj5j) in quinn-proto 0.11.14 allowed attackers to exhaust server memory through unbounded out-of-order QUIC stream reassembly. The fix upgrades to quinn-proto 0.11.15, which implements proper bounds checking to prevent malicious clients from forcing servers to buffer unlimited out-of-order stream data.
The quinn-proto library, a critical component for QUIC protocol implementations, contained a denial of service vulnerability (CVE-2026-31812) that could be triggered by specially crafted QUIC Initial packets. A security update from version 0.11.13 to 0.11.14 tightens the handling of untrusted network input, preventing attackers from exhausting server resources through malformed packets.
A high-severity vulnerability in `quinn-proto` allowed remote attackers to exhaust server memory by sending carefully crafted out-of-order QUIC stream data, triggering unbounded buffer growth during reassembly. The fix upgrades `rustls-webpki` from `0.103.10` to `0.103.13` in `Cargo.lock`, closing a related denial-of-service primitive that could be chained with the stream reassembly weakness. Together, these changes harden the QUIC stack against memory exhaustion attacks that require no authenti
