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

high Tenable Cloud Security Plugin ID 476142

Description

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

 - In this scenario, libcurl first uses a proper HTTP/3 server for the initial transfers, and when it makes a
 second transfer to the same site it has been replaced by the attacker's impostor machine - without a valid
 certificate. When libcurl returns to the hostname the second time with a cached SSL session
 (`CURLOPT_SSL_SESSIONID_CACHE` is not disabled) and early data enabled (the `CURLSSLOPT_EARLYDATA` bit is
 set in `CURLOPT_SSL_OPTIONS`), libcurl might send off the second request's bytes on that new connection
 *before* enforcing the certificate verification failure. Potentially leaking sensitive information.
 (CVE-2026-9545)

Solution

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