Echo: jq: security update to 1.7.1-6+deb13u2+e3

high Tenable Cloud Security Plugin ID 459008

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,` jq --rawfile` can turn a handled oversized-string
 error into invalid-state reuse and a real heap out-of-bounds write in assertion-disabled builds. When
 jv_load_file(raw=1) reads an attacker-controlled file, it repeatedly appends file chunks to the same jv
 string accumulator. Once jv_string_append_buf() returns jv_invalid_with_msg("String too long"), the raw-
 file loop does not stop. If the file contains at least one more byte, the next loop iteration appends a
 new chunk to an object that is already invalid. With assertions enabled this aborts in jvp_string_ptr().
 With assertions disabled, the invalid object is interpreted as a string object and ASan reports heap-
 buffer-overflow. This vulnerability is fixed in 1.8.2. (CVE-2026-49839)

Solution

Update the jq library and its related packages to version 1.7.1-6+deb13u2+e3 or later.
