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/proftpd-mod-counter-0.6.2/mod_counter.c FINAL RESULTS: data/proftpd-mod-counter-0.6.2/mod_counter.c:237:3: [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[PR_TUNABLE_BUFFER_SIZE]; data/proftpd-mod-counter-0.6.2/mod_counter.c:262:10: [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). id = atoi(buf); data/proftpd-mod-counter-0.6.2/mod_counter.c:336:5: [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[32]; data/proftpd-mod-counter-0.6.2/mod_counter.c:718:11: [2] (integer) atoi: Unless checked, the resulting number can exceed the expected range (CWE-190).
