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/globus-authz-4.3/globus_gsi_authz.h Examining data/globus-authz-4.3/globus_gsi_authz.c Examining data/globus-authz-4.3/globus_gsi_authz_constants.h Examining data/globus-authz-4.3/globus_i_gsi_authz.h Examining data/globus-authz-4.3/globus_gsi_authz_error.c Examining data/globus-authz-4.3/test/authz_test_callout.c Examining data/globus-authz-4.3/test/authz_cred_test.c FINAL RESULTS: data/globus-authz-4.3/globus_gsi_authz.c:80:42: [2] (integer) atoi: Unless checked, the resulting number can exceed the expected range (CWE-190). If source untrusted, check both minimum and maximum, even if the input had no minus sign (large numbers can roll over into negative number; consider saving to an unsigned value if that is intended). globus_i_gsi_authz_debug_level = atoi(tmp_string); data/globus-authz-4.3/globus_gsi_authz.c:91:44: [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). globus_i_gsi_authz_debug_fstream = fopen(tmp_string, "a"); data/globus-authz-4.3/globus_gsi_authz_error.c:27:1: [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 * data/globus-authz-4.3/test/authz_cred_test.c:66:5: [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]; ANALYSIS SUMMARY: Hits = 4 Lines analyzed = 1616 in approximately 0.08 seconds (21059 lines/second) Physical Source Lines of Code (SLOC) = 1046 Hits@level = [0] 7 [1] 0 [2] 4 [3] 0 [4] 0 [5] 0 Hits@level+ = [0+] 11 [1+] 4 [2+] 4 [3+] 0 [4+] 0 [5+] 0 Hits/KSLOC@level+ = [0+] 10.5163 [1+] 3.82409 [2+] 3.82409 [3+] 0 [4+] 0 [5+] 0 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
