SUSE SLED15 / SLES15 Security Update : jq (SUSE-SU-2026:2983-1)

medium Nessus Plugin ID 326932

Language:

Synopsis

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

Description

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:2983-1 advisory.

 - CVE-2026-32316: integer overflow within the `jvp_string_append()` and `jvp_string_copy_replace_bad` functions can lead to heap buffer overflow when evaluating untrusted jq queries (bsc#1262044).
 - CVE-2026-33947: unbounded recursion in functions `jv_setpath()`, `jv_getpath()`, and `delpaths_sorted()` can lead to excessive resource consumption when processing crafted JSON input (bsc#1262069).
 - CVE-2026-39956: missing runtime type checks in `_strindices` and `jv_string_indexes()` can lead to a crash when evaluating untrusted jq filters against a release build (bsc#1262070).
 - CVE-2026-39979: incorrect processing of non-nul-terminated counted buffers in `jv_parse_sized` can lead to an out-of-bounds read when processing malformed JSON (bsc#1262071).
 - CVE-2026-40164: use of `MurmurHash3` with a hardcoded seed allows pre-computation of key collisions and can lead to a denial of service via resource exhaustion when processing crafted JSON objects (bsc#1262072).

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.
