Echo: multiple curl-8.1.1 packages: security update to 7.88.0

medium Tenable Cloud Security Plugin ID 476268

Description

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

 - A cleartext transmission of sensitive information vulnerability exists in curl <v7.88.0 that could cause
 HSTS functionality to behave incorrectly when multiple URLs are requested in parallel. Using its HSTS
 support, curl can be instructed to use HTTPS instead of using an insecure clear-text HTTP step even when
 HTTP is provided in the URL. This HSTS mechanism would however surprisingly fail when multiple transfers
 are done in parallel as the HSTS cache file gets overwritten by the most recentlycompleted transfer. A
 later HTTP-only transfer to the earlier host name would then *not* get upgraded properly to HSTS.
 (CVE-2023-23915)

Solution

Update the curl-8.1.1 library and its related packages to version 7.88.0 or later.
