openSUSE 16 Security Update : kea (openSUSE-SU-2026:20452-1)

high Nessus Plugin ID 304858

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-2026:20452-1 advisory.

Update to 3.0.3:

- CVE-2025-11232: invalid characters cause assert (bsc#1252863).
- CVE-2026-3608: stack overflow via maliciously crafted message (bsc#1260380).

Changelog:

* 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]
* When a hostname or FQDN received from a client is reduced to an empty string by hostname sanitizing, kea-dhcp4 and kea-dhcp6 will now drop the option.
(CVE-2025-11232) [bsc#1252863]
* 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.
* Removed logging an error in ping check hook library if using lease cache treshold.
* Fixed deadlock in ping-check hooks library.
* Fixed a data race in ping-check hooks library.

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 packages.
