SUSE SLES16 Security Update : jq (SUSE-SU-2026:22637-1)

medium Nessus Plugin ID 327564

Synopsis

The remote SUSE host is missing one or more security updates.

Description

The remote SUSE Linux SLES16 / SLES_SAP16 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:22637-1 advisory.

 This update for jq fixes the following issues

 - CVE-2026-43896: unbounded recursion in jv_object_merge_recursive() can lead to C stack exhaustion and a process crash (bsc#1265075).
 - CVE-2026-44777: uncontrolled recursion in ordinary module loader when two valid modules `include` each other can lead to stack exhaustion and process crash (bsc#1265076).
 - CVE-2026-49839: fixed a bug where 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 (bsc#1269220).
 - CVE-2026-54679: integer overflow in jvp_string_append can lead to a buffer overrun on 32-bit systems (bsc#1269390).

Tenable has extracted the preceding description block directly from the SUSE security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected jq, libjq-devel and / or libjq1 packages.
