Echo: jq: security update to 1.7.1-6+deb13u1+e2

medium Tenable Self-Hosted Container Security Plugin ID 465323

Description

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

 - jq is a command-line JSON processor. Prior to version 1.8.2, the _strindices builtin in jq's src/builtin.c
 passes its arguments directly to jv_string_indexes() without verifying they are strings, and
 jv_string_indexes() in src/jv.c relies solely on assert() checks that are stripped in release builds
 compiled with -DNDEBUG. This allows an attacker to crash jq trivially with input like _strindices(0), and
 by crafting a numeric value whose IEEE-754 bit pattern maps to a chosen pointer, achieve a controlled
 pointer dereference and limited memory read/probe primitive. Any deployment that evaluates untrusted jq
 filters against a release build is vulnerable. This issue has been patched in commit
 fdf8ef0f0810e3d365cdd5160de43db46f57ed03, which is part of version 1.8.2. (CVE-2026-39956)

Solution

Update the jq library and its related packages to version 1.7.1-6+deb13u1+e2 or later.
