Description ybuenos 2024-06-02 14:16:17 UTC 
An invalid pointer in the modbus_receive() function of libmodbus v3.1.6 allows attackers to cause a Denial of Service (DoS) via a crafted message sent to the unit-test-server.

Comment 2 Eric Sandeen 2024-07-17 16:23:44 UTC 
This is a duplicate of CVE-2024-36843 (and of bug #2284252), see discussion in https://github.com/stephane/libmodbus/issues/750.

The flaw is fixed in version 3.1.7 which is already present in all supported distributions, so closing NOTABUG.
