Flawfinder version 2.0.10, (C) 2001-2019 David A. Wheeler. Number of rules (primarily dangerous function names) in C/C++ ruleset: 223 Examining data/switchsh-0~20070801/switchsh.c FINAL RESULTS: data/switchsh-0~20070801/switchsh.c:65:38: [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. __attribute__ ((noreturn, format(printf, 1, 2))); data/switchsh-0~20070801/switchsh.c:67:38: [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. __attribute__ ((noreturn, format(printf, 1, 2))); data/switchsh-0~20070801/switchsh.c:121:5: [4] (shell) execvp: 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. execvp(*argv, argv); data/switchsh-0~20070801/switchsh.c:131:5: [4] (format) vfprintf: If format strings can be influenced by an attacker, they can be exploited (CWE-134). Use a constant for the format specification. vfprintf(stderr, fmt, ap); data/switchsh-0~20070801/switchsh.c:142:5: [4] (format) vfprintf: If format strings can be influenced by an attacker, they can be exploited (CWE-134).
