Netopeer crashes with invalid xml payload

[officialid12]

We are observing Netopeer crash when we do a edit-config or get operation with invalid xml payload.

Example:

With the below invalid xml payload seeing a crash when the sshd container is missed.

This crash happens even when we provide wrong interface name: ether1/4 or ethernet1/3/

I cannot help you, your version is more than 3 years old and whatever issue you find, it is not relevant for the current versions and only those are maintained.
