APM V8.1.4.0.20 May 2023 08.23.05.00
Fixed the following vulnerability issues:
  • CVE-2020-13956 - Apache HTTP Client versions prior to version 4.5.13 and 5.0.3 can misinterpret malformed authority components in request URIs passed to the library as java.net.URI object and pick the wrong target host for request execution.
  • CVE-2019-10202 - A series of deserialization vulnerabilities have been discovered in Codehaus 1.9.x implemented in EAP7. This CVE fixes CVE-2017-17485, CVE-2017-7525, CVE-2017-15095, CVE-2018-5968, CVE-2018-7489, CVE-2018-1000873, CVE-2019-12086 reported for FasterXML jackson-databind by implementing a allowlist approach that will mitigate these vulnerabilities and future ones alike.
  • CVE-2019-10172 - A flaw was found in org.codehaus.jackson:jackson-mapper-asl:1.9.x libraries
APM V8.1.4.0.19 November 2022 08.22.10.00 Added support for Red Hat Enterprise Linux (RHEL) 9.0 on x86_64 Operating System.
CP4MCM 2.3.0.2 August 2022 08.22.07.00
Added support for Red Hat Enterprise Linux (RHEL) 9.0 on x86_64 Operating System.
V8.1.4.0.17 October 2021 08.20.11.00
Implemented framework changes to support Microsoft Visual C++ 2013 libraries.
V8.1.4.0.14 December 2020 08.20.10.00
Added support to configure retry count for connection attempts in the event of connection failure.
V8.1.4.0.14 June 2020 08.20.06.00
  • The agent is upgraded to use Ovirt Java SDK 4.3. The agent can be upgraded from older release versions, however, from this release the agent will support RHVM 4.0 and above and there is no backward compatibility with older versions of RHVM.
  • Data provider is optimized to decrease the overall CPU consumption on Ovirt engine.
  • Live snapshot support attribute is deprecated in the Hosts attribute group.
  • Retry count is upgraded to limit the connection attempt with data source: A limit is added on number of retries the agent attempts to connect to the data source (RHVM or Hyper-V) if connection fails. The default number for retry attempt is 6. This value can be changed by setting the following variable in the agent instance specific environment file: KV1_DATA_PROVIDER_CONNECTION_RETRY_COUNT

    After exhausting the limit of configured connection attempts, if the agent fails to connect to the data source, it will stop attempting to connect and log the following message in the data provider log:

    NO MORE ATTEMPTS OF CONNECTION;STOPPING THE DATA COLLECTION, TO RESUME MONITORING PLEASE RESTART THE AGENT. TO HAVE MORE ATTEMPT OF CONNECTIONS, RESET THE VALUE OF THE VARIABLE KV1_DATA_PROVIDER_CONNECTION_RETRY_COUNT
