Abstract

The embodiment of the invention relates to the technical field of computers, in particular to a program vulnerability detection method and device, and aims at solving the problems that a large amountof manpower needs to be consumed in program crash detection and samples capable of causing program crash are scarce. The method comprises the steps of obtaining test samples in a test sample queue, and performing mutation processing on the test samples to obtain a plurality of mutation test samples corresponding to the test samples; inputting a plurality of mutation test samples into a detected program for execution to determine an index parameter of each mutation test sample, and when it is determined that no mutation test sample causing crash of the detected program exists in each mutation test sample, determining a mutation test sample of which the index parameter conforms to a preset condition from each mutation test sample, and adding the mutation test sample conforming to the presetcondition into the test sample queue to carry out the next round of test until a preset number of mutation test samples causing the crash of the detected program are determined.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular, to a program vulnerability detection method and device. Background technique [0002] With the development of computer technology, computer security issues and security risks are becoming more and more serious. Therefore, the analysis and mining of computer program loopholes to avoid malicious attacks is a hot spot that has attracted much attention. [0003] At present, for the mining of program vulnerabilities, most of the security researchers first capture and analyze samples that can cause program crashes to determine the cause of program crashes and determine the location of the crash. For test samples that can cause program crashes After analysis, if it is determined that the test sample can be used maliciously, the test sample that can cause the program to crash can be determined as a program vulnerability. It can be seen that the analysis of p...
