high Nessus Plugin ID 335941

Synopsis

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

Description

The remote openSUSE 16 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:21580-1 advisory.

Update to version 2.1.12.suse+0.8f77cf16:

- CVE-2026-44943: improper limitation of pathname to a restricted directory allows remote MITM attackers to create root-owned files outside the database and inject lines into records (bsc#1268353).
- CVE-2026-44944: incorrect authorization allows unpriviledged local users to use the `isscsiuio` control socket (bsc#1268352).

Changes for open-iscsi:

- Version 2.1.12.suse+0.8f77cf16:
* Fix security issues recently discovered by Keith at Linneman Labs.
* iscsi-init.service: use `iscsi-gen-initiatorname`.
* iscsi-gen-initiatorname: use `@IQN_PREFIX@` as default.
* Avoid possible double free of found in `idbm_rec_update_param`.
* iscsi: validate interface IP against target address family.

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 iscsiuio, libopeniscsiusr0, open-iscsi and / or open-iscsi-devel packages.
