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/dumb-init-1.2.2/VERSION.h Examining data/dumb-init-1.2.2/dumb-init.c FINAL RESULTS: data/dumb-init-1.2.2/dumb-init.c:25:5: [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, "[dumb-init] " __VA_ARGS__); \ data/dumb-init-1.2.2/dumb-init.c:319:9: [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(cmd[0], &cmd[0]); data/dumb-init-1.2.2/dumb-init.c:192:19: [3] (buffer) getopt_long: Some older implementations do not protect against internal buffer overflows (CWE-120, CWE-20). Check implementation on installation, or limit the size of all string inputs. while ((opt = getopt_long(argc, argv, "+hvVcr:", long_options, NULL)) != -1) { data/dumb-init-1.2.2/dumb-init.c:224:23: [3] (buffer) getenv: Environment variables are untrustable input if they can be set by an attacker. They can have any content and length, and the same variable can be set more than once (CWE-807, CWE-20). Check environment variables carefully before using them. char *debug_env = getenv("DUMB_INIT_DEBUG"); data/dumb-init-1.2.2/dumb-init.c:230:24: [3] (buffer) getenv: Environment variables are untrustable input if they can be set by an attacker. They can have any content and length, and the same variable can be set more than once (CWE-807, CWE-20). Check environment variables carefully before using them. char *setsid_env = getenv("DUMB_INIT_SETSID"); data/dumb-init-1.2.2/dumb-init.c:43:1: [2] (buffer) char: Statically-sized arrays can be improperly restricted, leading to potential overflows or other issues (CWE-119!/CWE-120). Perform bounds checking, use functions that limit length, or ensure that the size is larger than the maximum possible length. char signal_temporary_ignores[MAXSIG + 1] = {[0 ...
