Echo: curl: security update to 1:8.22.0-1+e1curl-8.17.0: security update to 8.17.0+e1

high Tenable Cloud Security Plugin ID 461428

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - When a user invokes curl using a schemeless URL combined with `--proto-default` sftp (or scp), a
 disconnect occurs between the tool layer and libcurl. The tool layer incorrectly infers the URL scheme,
 which erroneously bypasses the initialization of critical SSH security options like
 CURLOPT_SSH_HOST_PUBLIC_KEY_SHA256 and CURLOPT_SSH_KNOWNHOSTS. Conversely, the libcurl runtime
 successfully honors CURLOPT_DEFAULT_PROTOCOL and establishes the connection via SFTP/SCP as specified.
 Because the tool layer skipped the security configuration, these SSH host verification options are
 silently omitted, causing curl to connect to an unverified SSH remote host without throwing an error.
 (CVE-2026-12064)

Solution

Update the curl library and its related packages to version 1:8.22.0-1+e1 or later.
