[2.2.0] Checkmk Werk 16219 created: Limit length of Hostname

by Checkmk werks level 1

Title: Limit length of Hostname Class: security Compatible: compat Component: wato Date: 1699601325 Edition: cre Knowledge: undoc Level: 1 State: unknown Version: 2.2.0p15 Prior to this Werk it was possible to create Hosts with arbitrary length. Since Checkmk stores information in files which paths contain the hostname these path could exceed the allowed length leading to various errors to an extend that rendered the usage of parts of the GUI useless. We found this vulnerability internally. Affected Versions: LI: 2.2.0 LI: 2.1.0 LI: 2.0.0 Vulnerability Management: We have rated the issue with a CVSS Score of 2.7 (Low) with the following CVSS vector: <tt>CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:L</tt>. We assigned CVE-2023-23549 to this vulnerability. Changes: This Werk adds a maximum length of 253 characters for the hostname.

[2.2.0] Checkmk Werk 14216 created: Prevent LDAP users from disappearing at remote sites

by Checkmk werks level 1

Title: Prevent LDAP users from disappearing at remote sites Class: fix Compatible: compat Component: multisite Date: 1699364878 Edition: cre Knowledge: doc Level: 1 Version: 2.2.0p15 If a remote site had ldap connectors specified, which where not available at the central site, the users on the remote site were regularly removed during activate changes. This error was not always clearly visible, as the ldap users were resynchronised immediately after activate changes. However, this introduced race conditions, such as users not known to the monitoring core or automatic logouts at the remote site.

[2.2.0] Checkmk Werk 16228 created: Enable update as site user due incompatible python versions

by Checkmk werks level 1

Title: Enable update as site user due incompatible python versions Class: fix Compatible: compat Component: omd Date: 1699525492 Edition: cre Knowledge: doc Level: 1 Version: 2.2.0p14 This werk is relevant for you in case you've been using <tt>omd -V {version} update</tt> as site user. Due to the update of the Python version from 3.11.2 to 3.11.5 with 2.2.0p13, we needed to introduce a fix in order to avoid the following issue: C+: Traceback (most recent call last): File "/omd/versions/2.2.0p13.cee/bin/omd", line 60, in <module> import omdlib.main File "/omd/versions/2.2.0p13.cee/lib/python3/omdlib/main.py", line 36, in <module> import random File "/omd/versions/2.2.0p13.cee/lib/python3.11/random.py", line 49, in <module> from math import log as _log, exp as _exp, pi as _pi, e as _e, ceil as _ceil ImportError: /omd/versions/2.2.0p13.cee/lib/python3.11/lib-dynload/math.cpython-311-x86_64-linux-gnu.so: undefined symbol: _PyModule_Add C-: However, this fix introduced another issue with the release of 2.2.0p13, that's why we had to withdraw 2.2.0p13 and release 2.2.0p14 which addressed both issues.
