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/pgpdump-0.33/keys.c Examining data/pgpdump-0.33/os/riscos/config.h Examining data/pgpdump-0.33/packet.c Examining data/pgpdump-0.33/pgpdump.c Examining data/pgpdump-0.33/pgpdump.h Examining data/pgpdump-0.33/signature.c Examining data/pgpdump-0.33/subfunc.c Examining data/pgpdump-0.33/tagfuncs.c Examining data/pgpdump-0.33/types.c Examining data/pgpdump-0.33/uatfunc.c Examining data/pgpdump-0.33/buffer.c FINAL RESULTS: data/pgpdump-0.33/pgpdump.c:73:17: [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/pgpdump-0.33/pgpdump.c:86:17: [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/pgpdump-0.33/pgpdump.c:114:14: [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 ((c = getopt(argc, argv, "hvagilmpu")) != -1) data/pgpdump-0.33/buffer.c:438:2: [2] (buffer) memcpy: Does not check for buffer overflows when copying to destination (CWE-120). Make sure destination can always hold the source data. memcpy(d_buf2, NEXT_IN, AVAIL_COUNT); data/pgpdump-0.33/types.c:348:4: [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 temp[4]; data/pgpdump-0.33/buffer.c:125:7: [1] (buffer) getchar: Check buffer boundaries if used in a loop including recursive loops (CWE-120, CWE-20). c = getchar(); data/pgpdump-0.33/buffer.c:156:9: [1] (buffer) getchar: Check buffer boundaries if used in a loop including recursive loops (CWE-120, CWE-20). while (getchar() != EOF); data/pgpdump-0.33/packet.c:287:6: [1] (buffer) getchar: Check buffer boundaries if used in a loop including recursive loops (CWE-120, CWE-20). c = getchar(); ANALYSIS SUMMARY: Hits = 8 Lines analyzed = 3022 in approximately 0.08 seconds (36108 lines/second) Physical Source Lines of Code (SLOC) = 2334 Hits@level = [0] 273 [1] 3 [2] 2 [3] 1 [4] 2 [5] 0 Hits@level+ = [0+] 281 [1+] 8 [2+] 5 [3+] 3 [4+] 2 [5+] 0 Hits/KSLOC@level+ = [0+] 120.394 [1+] 3.42759 [2+] 2.14225 [3+] 1.28535 [4+] 0.856898 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
