Synopsis

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

Description

The remote SUSE Linux SLES12 / SLES_SAP12 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2026:4610-1 advisory.

- CVE-2026-90616: missing symlink protection allows a malicious sandboxed app to obtain arbitrary read and write access to files on the host (bsc#1280236).
- CVE-2026-92162: path traversal via unvalidated `arch` parameter in `DeployAppstream` (bsc#1282514).
- CVE-2026-96275: arbitrary write access as root via extra-data extraction (bsc#1282515).
- CVE-2026-96276: arbitrary write in host context via `flatpak build-init` (bsc#1282516).
- CVE-2026-96281: unprivileged active user can bypass anti-downgrade checks for system apps/runtimes (bsc#1282519).
- CVE-2026-96282: extension metadata path traversal file existence oracle (bsc#1282520).

- CVE-2026-96807: fixed-filename writes to arbitrary locations via symlink attack on `.ld.so` (bsc#1282523).
- CVE-2026-96808: `revokefs` symlink path traversal allows local privilege escalation via commit tampering (bsc#1282524).

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 flatpak, libflatpak0 and / or typelib-1_0-Flatpak-1_0 packages.
