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/wev-1.0.0/shm.c Examining data/wev-1.0.0/shm.h Examining data/wev-1.0.0/wev.c FINAL RESULTS: data/wev-1.0.0/wev.c:97:7: [4] (format) vprintf: If format strings can be influenced by an attacker, they can be exploited (CWE-134). Use a constant for the format specification. n += vprintf(fmt, ap); data/wev-1.0.0/wev.c:307:4: [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("\n" SPACER); data/wev-1.0.0/wev.c:839:16: [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. while ((opt = getopt(argc, argv, "f:F:ghM:")) != -1) { data/wev-1.0.0/wev.c:271:13: [2] (misc) fopen: 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). FILE *f = fopen(state->opts.dump_map, "w"); data/wev-1.0.0/wev.c:303:4: [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 buf[128]; data/wev-1.0.0/wev.c:341:2: [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 buf[128]; data/wev-1.0.0/shm.c:23:19: [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). randname(name + strlen(name) - 6); ANALYSIS SUMMARY: Hits = 12 Lines analyzed = 987 in approximately 0.04 seconds (24151 lines/second) Physical Source Lines of Code (SLOC) = 866 Hits@level = [0] 27 [1] 1 [2] 3 [3] 1 [4] 7 [5] 0 Hits@level+ = [0+] 39 [1+] 12 [2+] 11 [3+] 8 [4+] 7 [5+] 0 Hits/KSLOC@level+ = [0+] 45.0346 [1+] 13.8568 [2+] 12.7021 [3+] 9.23788 [4+] 8.08314 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
