high Tenable Cloud Security Plugin ID 476143

Description

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

 - libcurl's TFTP state machine fails to validate state transitions against the requested transfer direction,
 accepting opening server responses for both reads and writes interchangeably. A malicious TFTP server can
 respond to a download request in a way that forces the client into transmit mode, prompting libcurl to
 consume and transmit data from the handle's persistent `CURLOPT_READDATA` pointer - including data
 remaining from unrelated prior operations, such as an HTTP POST request executed on a reused handle.
 (CVE-2026-92389)

Solution

Update the curl library and its related packages to version 1:8.23.0-1+e1 or later.
