Echo: multiple curl-8.1.1 packages: security update to 7.87.0

high Tenable Cloud Security Plugin ID 476250

Description

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

 - A vulnerability exists in curl <7.87.0 HSTS check that could be bypassed to trick it to keep using HTTP.
 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. However, the HSTS mechanism could be bypassed if the host name
 in the given URL first uses IDN characters that get replaced to ASCII counterparts as part of the IDN
 conversion. Like using the character UTF-8 U+3002 (IDEOGRAPHIC FULL STOP) instead of the common ASCII full
 stop (U+002E) `.`. Then in a subsequent request, it does not detect the HSTS state and makes a clear text
 transfer. Because it would store the info IDN encoded but look for it IDN decoded. (CVE-2022-43551)

Solution

Update the curl-8.1.1 library and its related packages to version 7.87.0 or later.
