Fuzzing Risks in Software Tools


Fuzzing Risks in Software Tools

The residual risk of software failure after release is managed by giving the end user controls that help treat potential vulnerabilities. The most obvious is the ability of the user to refresh an application or reboot an operating system. In addition patches and upgrades are released during the life cycle of a software tool to assure the business continuity of the product. Our research question arose because of an unproven concern that bugs in software could be exploited for anti-forensic activity. A further worry was the potential misrepresentation or damage to evidence by vulnerabilities in both open source and proprietary tools. The research ran a number of test cases in which deliberately malformed data was input into digital forensic tools in an attempt to locate software bugs. The software bugs once located were then analysed and the potential for different exploitations identifi ed. We were successful in discovering a number of software bugs that resulted in unusual behaviour from different tools including behaviours that prevented evidence acquisition, crashing while searching or displaying incorrect evidence as well as evidence not being displayed.
