Echo: curl: security update to 1:8.14.1-2+deb13u3+e2

medium Tenable Self-Hosted Container Security Plugin ID 462782

Description

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

 - libcurl might in some circumstances reuse the wrong connection when asked to do an authenticated HTTP(S)
 request after a Negotiate-authenticated one, when both use the same host. libcurl features a pool of
 recent connections so that subsequent requests can reuse an existing connection to avoid overhead. When
 reusing a connection a range of criteria must be met. Due to a logical error in the code, a request that
 was issued by an application could wrongfully reuse an existing connection to the same server that was
 authenticated using different credentials. An application that first uses Negotiate authentication to a
 server with `user1:password1` and then does another operation to the same server asking for any
 authentication method but for `user2:password2` (while the previous connection is still alive) - the
 second request gets confused and wrongly reuses the same connection and sends the new request over that
 connection thinking it uses a mix of user1's and user2's credentials when it is in fact still using the
 connection authenticated for user1... (CVE-2026-5545)

Solution

Update the curl library and its related packages to version 1:8.14.1-2+deb13u3+e2 or later.
