Synopsis

The remote SUSE host is missing a security update.

Description

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by a vulnerability as referenced in the SUSE-SU-2026:1378-1 advisory.

Update to release 2.6.5:

* A large number of bracket pairs in a JSON payload directed to any endpoint would result in a stack overflow, due to recursive calls when parsing the JSON. This has been fixed.
(CVE-2026-3608) [bsc#1260380]
* A null dereference is now no longer possible when configuring the Control Agent with a socket that lacks the mandatory socket-name entry.
* UNIX sockets are now created as group-writable.
* Corrected an issue in logging configuration when parsing 'syslog:'
* Earlier Kea versions could crash when handling misconfigured global reservations. This has been fixed.
* Support for recent versions of Sphinx has been added.

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.
