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-proxy-ssl-6.2/library/proxypolicy.h Examining data/globus-gsi-proxy-ssl-6.2/library/proxycertinfo.h Examining data/globus-gsi-proxy-ssl-6.2/library/proxycertinfo.c Examining data/globus-gsi-proxy-ssl-6.2/library/proxypolicy.c Examining data/globus-gsi-proxy-ssl-6.2/test/test_proxycertinfo.c FINAL RESULTS: data/globus-gsi-proxy-ssl-6.2/library/proxycertinfo.c:340:5: [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 tmp_string[128]; data/globus-gsi-proxy-ssl-6.2/library/proxypolicy.c:193:9: [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(copy, policy, length); data/globus-gsi-proxy-ssl-6.2/library/proxypolicy.c:236:13: [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(copy, policy->policy->data, *length); data/globus-gsi-proxy-ssl-6.2/library/proxypolicy.c:271:5: [2] (buffer) char: Statically-sized arrays can be improperly restricted, leading to potential overflows or other issues (CWE-119!/CWE-120).

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). pclength = atoi(argv[ind]); data/globus-gsi-proxy-ssl-6.2/test/test_proxycertinfo.c:93:13: [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). instream = fopen(filename, "r"); data/globus-gsi-proxy-ssl-6.2/test/test_proxycertinfo.c:103:32: [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?
