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-gsi-credential-8.1/library/globus_gsi_credential.c Examining data/globus-gsi-credential-8.1/library/globus_gsi_cred_handle_attrs.c Examining data/globus-gsi-credential-8.1/library/globus_i_gsi_credential.h Examining data/globus-gsi-credential-8.1/library/globus_gsi_cred_error.c Examining data/globus-gsi-credential-8.1/library/globus_gsi_cred_handle.c Examining data/globus-gsi-credential-8.1/library/globus_gsi_cred_constants.h Examining data/globus-gsi-credential-8.1/library/globus_gsi_credential.h FINAL RESULTS: data/globus-gsi-credential-8.1/library/globus_gsi_credential.c:1883:5: [5] (race) chmod: This accepts filename arguments; if an attacker can move those files, a race condition results. (CWE-362). Use fchmod( ) instead. chmod(proxy_filename, S_IRWXU); data/globus-gsi-credential-8.1/library/globus_gsi_cred_error.c:30:1: [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-gsi-credential-8.1/library/globus_gsi_cred_handle.c:1287:13: [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(policy_string, data/globus-gsi-credential-8.1/library/globus_gsi_cred_handle.c:1308:9: [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(final_policy_string, policy_string, policy_string_length); data/globus-gsi-credential-8.1/library/globus_gsi_credential.c:72:41: [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_cred_debug_level = atoi(tmp_string); data/globus-gsi-credential-8.1/library/globus_gsi_credential.c:83:43: [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_cred_debug_fstream = fopen(tmp_string, "a"); data/globus-gsi-credential-8.1/library/globus_gsi_credential.c:1524:5: [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 password[100]; data/globus-gsi-credential-8.1/library/globus_gsi_cred_handle.c:1273:36: [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). policy_string_length = strlen(GLOBUS_NULL_POLICY); data/globus-gsi-credential-8.1/library/globus_gsi_credential.c:1417:28: [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). BIO_write(bp, pem_buf, strlen(pem_buf)); data/globus-gsi-credential-8.1/library/globus_gsi_credential.c:1655:47: [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). strlen(password)); ANALYSIS SUMMARY: Hits = 10 Lines analyzed = 6149 in approximately 0.11 seconds (55479 lines/second) Physical Source Lines of Code (SLOC) = 4120 Hits@level = [0] 0 [1] 3 [2] 6 [3] 0 [4] 0 [5] 1 Hits@level+ = [0+] 10 [1+] 10 [2+] 7 [3+] 1 [4+] 1 [5+] 1 Hits/KSLOC@level+ = [0+] 2.42718 [1+] 2.42718 [2+] 1.69903 [3+] 0.242718 [4+] 0.242718 [5+] 0.242718 Dot directories skipped = 1 (--followdotdir overrides) Minimum risk level = 1 Not every hit is necessarily a security vulnerability.
