Alpine: libcurl, multiple curl packages: security update to 8.14.0-r0

medium Tenable Cloud Security Plugin ID 427806

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

 - libcurl accidentally skips the certificate verification for QUIC connections when connecting to a host
 specified as an IP address in the URL. Therefore, it does not detect impostors or man-in-the-middle
 attacks. (CVE-2025-4947)

 - 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. (CVE-2025-5025)
