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

Description

The remote openSUSE 16 host has a package installed that is affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:20709-1 advisory.

Changes in tor:

- Update to 0.4.9.8
* Fix out-of-bounds read (boo#1264341, CVE-2026-44597, TROVE-2026-011)
* Do not attempt or accept BEGIN_DIR via conflux legs (boo#1264342, CVE-2026-44599,TROVE-2026-008)
* Adjust conflux out-of-order queue accounting when clearing a queue (boo#1264343, CVE-2026-44600, TROVE-2026-010)
* Fix a client-side crash caused by double-close of a circuit while under circuit queue memory pressure (boo#1264344, CVE-2026-44601, TROVE-2026-009)
* Fix null pointer dereference when receiving a CERT cell out of order (boo#1264345, CVE-2026-44602, TROVE-2026-006)
* Fix off-by-one out-of-bounds read if a malformed BEGIN cell is received (boo#1264346, CVE-2026-44603, TROVE-2026-007)

- upate to 0.4.9.5:
* first stable release in the 0.4.9 series
* introduces a new circuit-level encryption design for better client security
* introduce a more scalable way for large relay operators to annotate which relays they run so clients can avoid using too many of them in a single circuit

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
