Number of rules (primarily dangerous function names) in C/C++ ruleset: 223 Examining data/chrootuid-1.3/chrootuid.c FINAL RESULTS: data/chrootuid-1.3/chrootuid.c:180:12: [4] (shell) execv: This causes a new program to execute and is difficult to use safely (CWE-78). try using a library call that implements the same functionality if available. (void) execv(argv[3+optstart], argv + 3+optstart); data/chrootuid-1.3/chrootuid.c:144:9: [3] (misc) chroot: chroot can be very helpful, but is hard to use correctly (CWE-250, CWE-22). Make sure the program immediately chdir("/"), closes file descriptors, and drops root privileges, and that all necessary files (and no more!) are in the new root. if (chroot(argv[1+optstart])) { ANALYSIS SUMMARY: Hits = 2 Lines analyzed = 187 in approximately 0.06 seconds (2940 lines/second) Physical Source Lines of Code (SLOC) = 102 Hits@level = [0] 16 [1] 0 [2] 0 [3] 1 [4] 1 [5] 0 Hits@level+ = [0+] 18 [1+] 2 [2+] 2 [3+] 2 [4+] 1 [5+] 0 Hits/KSLOC@level+ = [0+] 176.471 [1+] 19.6078 [2+] 19.6078 [3+] 19.6078 [4+] 9.80392 [5+] 0 Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
