Echo: jq: security update to 1.7.1-6+deb13u3+e1

medium Tenable Cloud Security Plugin ID 460498

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 1.8.2, comparing two sufficiently deeply nested arrays with
 the == operator exhausts the C stack on jq's ordinary command-line surface, resulting in denial of service
 via stack exhaustion (uncontrolled recursion). The crash occurs in jq's recursive structural comparison
 code, with the recursion repeating through jvp_array_equal() and jv_equal() in src/jv.c when comparing
 deeply nested arrays; a nearby sort comparator path through jv_cmp() in src/jv_aux.c overflows the stack
 at a larger nesting depth from the same missing recursion guard. Anyone running jq comparisons on
 attacker-controlled deeply nested JSON values, or embedding jq in a context where untrusted data can reach
 the == comparison path, is affected. This vulnerability is fixed in 1.8.2. (CVE-2026-47770)

Solution

Update the jq library and its related packages to version 1.7.1-6+deb13u3+e1 or later.
