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

medium Tenable Self-Hosted Container Security Plugin ID 478509

Description

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

 - An authentication bypass vulnerability exists in libcurl prior to v8.0.0 where it reuses a previously
 established SSH connection despite the fact that an SSH option was modified, which should have prevented
 reuse. libcurl maintains a pool of previously used connections to reuse them for subsequent transfers if
 the configurations match. However, two SSH settings were omitted from the configuration check, allowing
 them to match easily, potentially leading to the reuse of an inappropriate connection. (CVE-2023-27538)

Solution

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