Echo: curl-7.69.1: security update to 7.69.1+e2

medium Tenable Cloud Security Plugin ID 478484

Description

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

 - An authentication bypass vulnerability exists in libcurl <8.0.0 in the FTP connection reuse feature that
 can result in wrong credentials being used during subsequent transfers. Previously created connections are
 kept in a connection pool for reuse if they match the current setup. However, certain FTP settings such as
 CURLOPT_FTP_ACCOUNT, CURLOPT_FTP_ALTERNATIVE_TO_USER, CURLOPT_FTP_SSL_CCC, and CURLOPT_USE_SSL were not
 included in the configuration match checks, causing them to match too easily. This could lead to libcurl
 using the wrong credentials when performing a transfer, potentially allowing unauthorized access to
 sensitive information. (CVE-2023-27535)

Solution

Update the curl-7.69.1 library and its related packages to version 7.69.1+e2 or later.
