Echo: curl: security update to 1:8.23.0-1+e1

critical Tenable Self-Hosted Container Security Plugin ID 476130

Description

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

- When an FTP wildcard `LIST` operation fails, libcurl omits the restoration path meant for successful
listings, leaving the write callback set to the internal listing parser and the write callback data
pointing directly to the easy handle. Subsequent reuse of this handle triggers an immediate crash, and
cloning it via `curl_easy_duphandle()` copies this corrupted state into the duplicate. If the original
handle is subsequently freed, executing a transfer on the cloned handle causes a heap use-after-free read
against the dangling handle reference; alternatively, reusing the original or cloned handle while changing
only `CURLOPT_WRITEDATA` (and omitting `CURLOPT_WRITEFUNCTION`) results in type confusion, forcing the
internal parser to interpret incoming server response bytes into memory at the application-supplied write
data pointer. (CVE-2026-92388)

Solution

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