Tanium Cloud Release Notes Quarantine
Release Date: October 25, 2022
Fix
- Fixes an issue where IR Quarantine on Linux sets the CIDR to 0 and IP to 0.0.0.0 instead of setting the CIDR to 32 when a custom rule has a blank CIDR.
Security Update
- This release includes security updates. Details of the issue, including affected versions, and mitigation information, can be obtained within Tanium's Support Portal, or by contacting your TAM.
Known Issue
- When using quarantine rules to block the ICMP protocol, the MTU negotiation packages can become blocked when the size of the MTU package on the endpoint is larger than the routers allowed MTU size. Normally the router will see a packet that is too large and send an ICMP packet to the endpoint to identify that the packet is too large and advises lowering the permissible MTU size. If the negotiation packet is not able to reach the destination due to quarantine, the endpoint can become unresponsive. The endpoint is still is quarantined but loses communication with the Tanium server. Disable ICMP at your own risk.
Release Date: April 27, 2022
