Number of rules (primarily dangerous function names) in C/C++ ruleset: 223 Examining data/automake1.11-1.11.6/lib/ansi2knr.c Examining data/automake1.11-1.11.6/doc/amhello/src/main.c FINAL RESULTS: data/automake1.11-1.11.6/lib/ansi2knr.c:270:4: [4] (format) fprintf: If format strings can be influenced by an attacker, they can be exploited (CWE-134). Use a constant for the format specification. fprintf(stderr, usage); data/automake1.11-1.11.6/lib/ansi2knr.c:276:3: [4] (format) fprintf: If format strings can be influenced by an attacker, they can be exploited (CWE-134).
