Number of rules (primarily dangerous function names) in C/C++ ruleset: 223 Examining data/hsetroot-1.0.2/src/hsetroot.c FINAL RESULTS: data/hsetroot-1.0.2/src/hsetroot.c:16:3: [4] (format) printf: If format strings can be influenced by an attacker, they can be exploited (CWE-134). Use a constant for the format specification. printf (PACKAGE_STRING " - " DESCRIPTION "\n" data/hsetroot-1.0.2/src/hsetroot.c:155:8: [1] (buffer) strlen: Does not handle strings that are not \0-terminated; if given one it may perform an over-read (it could cause a crash if unprotected) (CWE-126). if ((strlen (arg) != 7) && (strlen (arg) != 9)) data/hsetroot-1.0.2/src/hsetroot.c:155:31: [1] (buffer) strlen: Does not handle strings that are not \0-terminated; if given one it may perform an over-read (it could cause a crash if unprotected) (CWE-126). if ((strlen (arg) != 7) && (strlen (arg) != 9)) data/hsetroot-1.0.2/src/hsetroot.c:162:7: [1] (buffer) strlen: Does not handle strings that are not \0-terminated; if given one it may perform an over-read (it could cause a crash if unprotected) (CWE-126). if (strlen (arg) == 9) ANALYSIS SUMMARY: Hits = 4 Lines analyzed = 675 in approximately 0.06 seconds (10661 lines/second) Physical Source Lines of Code (SLOC) = 613 Hits@level = [0] 47 [1] 3 [2] 0 [3] 0 [4] 1 [5] 0 Hits@level+ = [0+] 51 [1+] 4 [2+] 1 [3+] 1 [4+] 1 [5+] 0 Hits/KSLOC@level+ = [0+] 83.1974 [1+] 6.52529 [2+] 1.63132 [3+] 1.63132 [4+] 1.63132 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
