curl: Missing applicability validation allows non-applicable HTTPS RR to reach ECH processing

Summary The HTTPS RR applicability check Curlhttpsrrapplicable is applied before ALPN selection, but the same check is not applied consistently in the ECH initialization paths. When an HTTPS RR is not applicable to the active connection, curl correctly reports it as not applicable and avoids usin...

Astra Linux – Vulnerability in Wireshark

The TLS ECH decryptor module crashes in Wireshark versions 4.6.0 to 4.6.6, allowing denial of service attacks...

Medium: runc

Issue Overview: x509.Certificate.VerifyHostname previously called matchHostnames in a loop over all DNS Subject Alternative Name SAN entries. This caused strings.Splithost, "." to execute repeatedly on the same input hostname. With a large DNS SAN list, verification costs scaled quadratically bas...
