Echo: curl-7.69.1: security update to 7.69.1+e1

high Tenable Self-Hosted Container Security Plugin ID 476260

Description

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

 - libcurl-using applications can ask for a specific client certificate to be used in a transfer. This is
 done with the `CURLOPT_SSLCERT` option (`--cert` with the command line tool).When libcurl is built to use
 the macOS native TLS library Secure Transport, an application can ask for the client certificate by name
 or with a file name - using the same option. If the name exists as a file, it will be used instead of by
 name.If the appliction runs with a current working directory that is writable by other users (like
 `/tmp`), a malicious user can create a file name with the same name as the app wants to use by name, and
 thereby trick the application to use the file based cert instead of the one referred to by name making
 libcurl send the wrong client certificate in the TLS connection handshake. (CVE-2021-22926)

Solution

Update the curl-7.69.1 library and its related packages to version 7.69.1+e1 or later.
