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

medium Tenable Cloud Security Plugin ID 458096

Description

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

 - jq is a command-line JSON processor. In commits before 2f09060afab23fe9390cce7cb860b10416e1bf5f, the
 jv_parse_sized() API in libjq accepts a counted buffer with an explicit length parameter, but its error-
 handling path formats the input buffer using %s in jv_string_fmt(), which reads until a NUL terminator is
 found rather than respecting the caller-supplied length. This means that when malformed JSON is passed in
 a non-NUL-terminated buffer, the error construction logic performs an out-of-bounds read past the end of
 the buffer. The vulnerability is reachable by any libjq consumer calling jv_parse_sized() with untrusted
 input, and depending on memory layout, can result in memory disclosure or process termination. The issue
 has been patched in commit 2f09060afab23fe9390cce7cb860b10416e1bf5f. (CVE-2026-39979)

Solution

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