Описание
libcurl supports pinning of the server certificate public key for HTTPS transfers. Due to an omission, this check is not performed when connecting with QUIC for HTTP/3, when the TLS backend is wolfSSL. Documentation says the option works with wolfSSL, failing to specify that it does not for QUIC and HTTP/3. Since pinning makes the transfer succeed if the pin is fine, users could unwittingly connect to an impostor server without noticing.
A flaw was found in libcurl. This vulnerability can allow an attacker to connect to an imposter server via HTTP/3 QUIC connections when using the wolfSSL TLS backend, bypassing certificate pinning verification.
This issue only affects instances of curl and libcurl using WolfSSL as the backend TLS library.
Отчет
This vulnerability doesn't impact any Red Hat supported curl versions, as Red Hat doesn't ship the WolfSSL TLS library in any product.
