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/paxctl-0.9/paxctl-elf.c Examining data/paxctl-0.9/paxctl.c Examining data/paxctl-0.9/paxctl.h FINAL RESULTS: data/paxctl-0.9/paxctl.c:192:12: [3] (buffer) getopt: 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. switch(getopt(argc, state->argv, "pPsSmMeErRxXvqQzcC")) { data/paxctl-0.9/paxctl.c:41:3: [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 buffer[2 * num_pax_flags + 1]; data/paxctl-0.9/paxctl.c:111:8: [2] (misc) open: Check when opening files - can an attacker redirect it (via symlinks), force the opening of special file type (e.g., device files), move things around to create a race condition, control its ancestors, or change its contents? (CWE-362). fd = open(state->argv[state->files], oflags); ANALYSIS SUMMARY: Hits = 3 Lines analyzed = 679 in approximately 0.03 seconds (21670 lines/second) Physical Source Lines of Code (SLOC) = 551 Hits@level = [0] 22 [1] 0 [2] 2 [3] 1 [4] 0 [5] 0 Hits@level+ = [0+] 25 [1+] 3 [2+] 3 [3+] 1 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 45.3721 [1+] 5.44465 [2+] 5.44465 [3+] 1.81488 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
