Detailed vulnerability description
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists due to NULL pointer dereference in the ROS dissector when validating an OID. A remote attacker can inject a malformed packet epan/dissectors/asn1/ros/packet-ros-template.c onto the wire or persuade the target user to read a malformed packet trace file and cause the application to crash.
Successful exploitation of the vulnerability results in denial of service.
