Check_MK Werk 5919: Windows agent crashed with a lot of transport protocols available

by Jukka Aro

ID: 5919 Title: Windows agent crashed with a lot of transport protocols available Component: Checks & agents Level: 1 Class: Bug fix Version: 1.5.0i4 Werk #5704 introduced querying the supported IP families (IPv4/IPv6) upon agent start. This query makes use of the WinAPI function WSCEnumProtocols. This function turned out to contain a severe bug: if the protocol buffer passed as in/out parameter is not big enough to accommodate all available transport protocols, the function corrupts the heap by writing to memory past the buffer. This violates the MSDN documentation of WSCEnumProtocols, also the example code attached to the documentation is broken. So far, the bug has only been reported on older 32 bit systems (Windows Server 2008). However, the real extent of the problem is not known as there are no bug reports about WSCEnumProtocols publicly available to determine, if the function is broken in all Windows versions or just in some. A key factor is the number of configured/supported transport protocols: if the number grows large enough, WSCEnumProtocols causes the described buffer overflow. Now the use of WSCEnumProtocols has been changed so that - on the contrary to the documentation in MSDN - the function is always called twice to prevent the buffer overflow by allocating the necessary buffer only after first querying the necessary buffer size.

Check_MK Werk 5896: Improved output of Check_MK services

by Lars Michelsen

ID: 5896 Title: Improved output of Check_MK services Component: Core & setup Level: 1 Class: Bug fix Version: 1.5.0i4 <ul> <li>The result of the different data sources was not visible to the user in the Check_MK service.</li> <li>The Check_MK service is now showing individual status information about each data source (e.g. the agent version).</li> <li>The Check_MK HW/SW Inventory and Check_MK Discovery services are only showing data source related details in case a problem happened for a data source.</li> <li>The states of Check_MK, Check_MK Discovery and Check_MK HW/SW Inventory are now working in the same way (and all respect the "Check_MK service" ruleset) settings. This makes e.g. the Check_MK Discovery service result in CRIT states e.g. in case of agent communication errors when there is no cache file present where it previously only reported a WARN state.</li> </ul>

Check_MK Werk 5897: Agent connection errors are now treated as connection errors again

by Lars Michelsen

ID: 5897 Title: Agent connection errors are now treated as connection errors again Component: Core & setup Level: 1 Class: Bug fix Version: 1.5.0i4 Agent connection related issues are now treated as connection issues again by the "Check_MK" service. Connection errors result in CRITICAL states instead of UNKNOWN. This is also relevant when one uses the ruleset "Status of the Check_MK service" to override the default states.
