Echo: curl-8.8.0: security update to 8.8.0+e2

medium Tenable Cloud Security Plugin ID 478487

Description

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

 - libcurl's URL API function [curl_url_get()](https://curl.se/libcurl/c/curl_url_get.html) offers punycode
 conversions, to and from IDN. Asking to convert a name that is exactly 256 bytes, libcurl ends up reading
 outside of a stack based buffer when built to use the *macidn* IDN backend. The conversion function then
 fills up the provided buffer exactly - but does not null terminate the string. This flaw can lead to stack
 contents accidently getting returned as part of the converted string. (CVE-2024-6874)

Solution

Update the curl-8.8.0 library and its related packages to version 8.8.0+e2 or later.
