Echo: onnx: security update to 1.17.0-3+e6

medium Tenable Self-Hosted Container Security Plugin ID 478337

Description

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

 - In ONNX before 1.21.0, the 'save_external_data' function builds the external-data file path from the
 model's external_data location field and opens it for writing without 'O_NOFOLLOW/O_EXCL', after a non-
 atomic 'os.path.isfile()' check. A local attacker with write access to the directory where a victim
 serializes external data can deterministically pre-plant a symlink that is being followed, causing the
 victim's write to append to any file the victim can write, e.g. ~/.ssh/authorized_keys, cron files, or
 application configs. Fixed in 1.21.0. (CVE-2026-49114)

Solution

Update the onnx library and its related packages to version 1.17.0-3+e6 or later.
