The invention relates to the field of computer security, in particular to a method for repairing software vulnerabilities. The method includes the steps that 1, when software is installed, a vulnerability detection module detects whether vulnerabilities exist in the software; 2, when the vulnerability detection module detects the vulnerabilities, the vulnerabilities are compared with vulnerabilityinformation in a software vulnerability database; 3, the matched vulnerability information is found, and an intelligent repairing module extracts a repairing mode from the software vulnerability database to repair the vulnerabilities, and when no matched vulnerability information is found, the software vulnerability database automatically has access to a server to update vulnerability features and repairing files to repair the vulnerabilities. The intelligent repairing module can locally and rapidly repair the vulnerabilities according to the vulnerability information and the repairing mode in the vulnerability database, and therefore repairing time is shortened. For vulnerabilities without repairing success, vulnerability features and the repairing files are updated to repair the vulnerabilities again, and therefore the repairing rate is further increased for the vulnerabilities.
