Number of rules (primarily dangerous function names) in C/C++ ruleset: 223 Examining data/libcrypt-blowfish-perl-2.14/blowfish.h Examining data/libcrypt-blowfish-perl-2.14/_blowfish.c FINAL RESULTS: data/libcrypt-blowfish-perl-2.14/blowfish.h:3:18: [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. typedef unsigned char bf_cblock[8]; data/libcrypt-blowfish-perl-2.14/_blowfish.c:429:8: [1] (buffer) strncpy: Easily used incorrectly; doesn't always \0-terminate or check for invalid pointers [MS-banned] (CWE-120). Risk is low because the source is a constant string. strncpy((char *)bfkey, "Bad initialization data",24); data/libcrypt-blowfish-perl-2.14/_blowfish.c:444:3: [1] (buffer) strncpy: Easily used incorrectly; doesn't always \0-terminate or check for invalid pointers [MS-banned] (CWE-120). Risk is low because the source is a constant string. strncpy((char *)bfkey, "Error in crypt_block routine",29); ANALYSIS SUMMARY: Hits = 3 Lines analyzed = 483 in approximately 0.03 seconds (16051 lines/second) Physical Source Lines of Code (SLOC) = 397 Hits@level = [0] 0 [1] 2 [2] 1 [3] 0 [4] 0 [5] 0 Hits@level+ = [0+] 3 [1+] 3 [2+] 1 [3+] 0 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 7.55668 [1+] 7.55668 [2+] 2.51889 [3+] 0 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
