Abstract: C language has complicated semantics for integers. Integer errors lead to serious software failures or exploitable vulnerabilities while they are harbored in various real-world programs. It is labor-intensive and error-prone to manually address integer errors. The usability of existing automated techniques is generally poor, as they heavily rely on external specifications or simply transform bugs into crash. We propose RABIEF, a novel and fully automatic approach to fix C integer errors based on range analysis. RABIEF is inspired by the following insights: (1) fixes for various integer errors have typical patterns including sanitization, explicit cast and declared type alteration; (2) range analysis provides sound basis for error detection and guides fix generation. We implemented RABIEF into a tool Argyi. Its effectiveness and efficiency have been substantiated by the facts that: (1) Argyi succeeds in fixing 93.9% of 5414 integer bugs from Juliet test suite, scaling to 600 KLOC within 5500 seconds; (2) Argyi is confirmed to correctly fix 20 errors from 4 real-world programs within only 240 seconds.
