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

medium Tenable Cloud Security Plugin ID 463990

Description

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

 - libcurl might in some circumstances reuse the wrong connection when asked to do Negotiate-authenticated
 ones, even when they are set to use different "services". libcurl features a pool of recent connections so
 that subsequent requests can reuse an existing connection to avoid overhead. When reusing a connection a
 range of criteria must be met. Due to a logical error in the code, a request that was issued by an
 application could wrongfully reuse an existing connection to the same server that was authenticated using
 different services. (CVE-2026-8458)

Solution

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