Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 / openSUSE 15 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2022:1435-1 advisory.

Security fixes for golang-github-prometheus-prometheus:

- CVE-2022-21698: Denial of Service through unbounded cardinality, and potential memory exhaustion, when handling requests with non-standard HTTP methods (bsc#1196338).

Other non security changes for golang-github-prometheus-prometheus:

- Build `firewalld-prometheus-config` only for SUSE Linux Enterprise 15, 15-SP1 and 15-SP2, and require `firewalld`.
- Only recommends `firewalld-prometheus-config` as prometheus does not require it to run.
- Create `firewalld-prometheus-config` subpackage (bsc#1197042, jsc#SLE-24373, jsc#SLE-24374, jsc#SLE-24375)

Other non security changes for firewalld:
- Provide dummy `firewalld-prometheus-config` package (bsc#1197042)

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

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