Problems solved by technology

However, the execution of the program on the same path may produce different memory states, for example, different iterations in the same loop, different memory layouts, and different values ​​​​of variables. Therefore, only focusing on path coverage to find vulnerabilities will ignore A batch of memory corruption vulnerabilities that require a specific memory state to trigger

Abstract

The invention provides a fuzzy test method. The method comprises the following steps of: selecting a predetermined number of seeds from a seed pool; mutating the selected seeds to generate a pluralityof program inputs; monitoring the running state of a target program which has received the program inputs, and obtaining memory state information of a test process; determining an average memory state space of the current test according to the acquired memory state information; aiming at the seeds participating in the test in the seed pool, respectively comparing memory state space correspondingto each seed with the average memory state space; and reserving the seeds of which the memory state space is greater than the average memory state space. The invention also provides a device for realizing a fuzzy test, electronic equipment and a computer readable storage medium.

Description

technical field [0001] This specification relates to the technical field of software testing, and in particular to a fuzzing testing method, device, electronic equipment and computer-readable storage medium. Background technique [0002] Fuzz testing technology is a technology that automatically generates a large number of random inputs (testcases) to test the target program and discover vulnerabilities. In order to increase the control of random inputs in fuzz testing and enable fuzz testing to dig out vulnerabilities more efficiently, existing fuzz testing techniques use various feedback information generated by testcases that have already been executed to guide the generation of inputs. Among them, the fuzz testing technology based on path coverage feedback is a technology based on the execution path information that has been covered by executed testcases, and uses a specific algorithm to direct the execution path of the program to an unexecuted path to mine vulnerabiliti...
