Checkmk Werk 15424: Agent Bakery: Show full agent hash in GUI

by Andreas Umbreit

ID: 15424 Title: Agent Bakery: Show full agent hash in GUI Component: agents Level: 1 Class: Bug fix Version: 2.3.0b1 The agent hashes of baked agent packages, as shown in the available agents table in the agent bakery GUI, now are shown entirely, rather than abbreviated to 8 digits. While there is little benefit in abbreviating the hash, it turned out to be tedious to look up the full hash on the GUI.

Checkmk Werk 15422: Agent Bakery: New default UNIX agent folder permissions

by Andreas Umbreit

ID: 15422 Title: Agent Bakery: New default UNIX agent folder permissions Component: agents Level: 1 Class: Bug fix Version: 2.3.0b1 This change will be compatible for most, if not all, users. You are only affected if you actually make use of the (now removed) group-writable flag on agent package folders. Normally, (especially when using the agent updater) the checkmk agent package files/folders will be installed with root ownership, while metadata of pre-existing folders won't be altered by the installation. Hence, only customized installation methods (e.g., unpacking the tar package with a special user) may possibly run into problems with this change. Previously, the folders of a baked UNIX agent package were packaged with octal permissions of <tt>775</tt>. This lead to problems in some rare cases, e.g. when storing (and using) an ssh-id under an agent folder. This has now been changed to <tt>755</tt>, as the agent's folders are owned by root and also installed under folders owned by root by default. Please note that these are the permissions of the folders as they are packaged by the agent bakery. Depending on the package manager (or <tt>tar</tt> unpack command) and the target system's umask, the installed folders may end up with other permissions.

Checkmk Werk 15411: Render temperature units consistently with space in service outputs

by Joerg Herbel

ID: 15411 Title: Render temperature units consistently with space in service outputs Component: Checks & agents Level: 1 Class: Bug fix Version: 2.3.0b1 Depending on the underlying check plugin, Checkmk rendered temperature units with or without a space in service outputs. As of this werk, Checkmk consistently renders temperatures with a space between the numerical value and the unit. Examples: LI: 12.0 °C instead of 12.0°C LI: 256.41 K instead of 256.41 K

Checkmk Werk 15423: Linux agent: Handle failing symmetric encryption

by Andreas Umbreit

ID: 15423 Title: Linux agent: Handle failing symmetric encryption Component: Checks & agents Level: 1 Class: Security fix Version: 2.3.0b1 Prior to this Werk the symmetric encryption of agent data (if configured) would fail silently if the option "Run agent as non-root user (Linux)" was also set, since these two options are not compatible. As a result, agent output would be sent unencrypted. If symmetric encryption is configured, but failing, the agent will now abort immediately and transmit a message about the failure as the only output. This will then be reported at the Check_MK Agent service of the host, alongside a <tt>CRIT</tt> status. Affected Versions: LI: 2.2.0 (beta) LI: 2.1.0 LI: 2.0.0 LI: 1.6.0 (EOL) Vulnerability Management: We have rated the issue with a CVSS Score of 3.7 (Low) with the following CVSS vector: <tt>CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N</tt>. We have assigned CVE <tt>CVE-2023-1768</tt>.
